Niedomykalność zastawki aortalnej
Etiologia i przyczyny

Niedomykalność zastawki aortalnej (AR) charakteryzuje się wstecznym przepływem krwi z aorty do lewej komory podczas rozkurczu, co prowadzi do przeciążenia objętościowego LK. Etiologia AR jest wieloczynnikowa i obejmuje wady wrodzone (np. dwupłatkowa zastawka aortalna – najczęstsza przyczyna w USA), infekcyjne zapalenie wsierdzia, gorączkę reumatyczną, zwyrodnienie śluzakowate, zwapnienie zastawki oraz patologie aorty, takie jak rozwarstwienie aorty i poszerzenie aorty wstępującej. Choroby tkanki łącznej (zespół Marfana, Ehlersa-Danlosa), choroby reumatologiczne (zesztywniające zapalenie stawów kręgosłupa, toczeń rumieniowaty układowy) oraz infekcje (kiła, choroba Whipple’a) również mogą przyczyniać się do rozwoju AR. Ostre AR najczęściej wynika z infekcyjnego zapalenia wsierdzia, rozwarstwienia aorty lub urazu klatki piersiowej, natomiast przewlekła forma rozwija się stopniowo, często w przebiegu wrodzonych wad zastawki, zwyrodnienia związane z wiekiem lub poszerzenia aorty.

Etiologia niedomykalności zastawki aortalnej

Niedomykalność zastawki aortalnej (aortic valve regurgitation) to stan, w którym zastawka aortalna nie zamyka się prawidłowo, powodując wsteczny przepływ krwi z aorty do lewej komory serca podczas rozkurczu. Etiologia tego schorzenia jest złożona i może wynikać z wielu różnych przyczyn, które można podzielić na kilka głównych kategorii.12

Wrodzone wady zastawki aortalnej

Wady wrodzone stanowią istotną przyczynę niedomykalności zastawki aortalnej. Najczęstszą wadą wrodzoną prowadzącą do niedomykalności jest dwupłatkowa zastawka aortalna (bicuspid aortic valve), występująca u osób, które rodzą się z zastawką mającą tylko dwa płatki zamiast prawidłowych trzech. Ta wada jest najczęstszą wrodzoną przyczyną niedomykalności zastawki aortalnej w Stanach Zjednoczonych.134

Inne wrodzone anomalie zastawki aortalnej, które mogą prowadzić do jej niedomykalności, obejmują:

  • Jednopłatkową zastawkę aortalną (unicuspid valve)5
  • Czteropłatkową zastawkę aortalną (quadricuspid valve)6
  • Zrośnięte płatki zastawki7

Zmiany zapalne zastawki

Infekcyjne zapalenie wsierdzia (infective endocarditis) jest jedną z głównych przyczyn ostrej niedomykalności zastawki aortalnej. Jest to zakażenie wewnętrznej wyściółki serca, w tym zastawek, najczęściej spowodowane przez bakterie. Infekcja może prowadzić do zniszczenia lub perforacji płatków zastawki aortalnej.138

Gorączka reumatyczna (rheumatic fever), niegdyś najczęstsza przyczyna niedomykalności zastawki aortalnej, obecnie rzadziej spotykana w krajach rozwiniętych dzięki stosowaniu antybiotyków w leczeniu infekcji paciorkowcowych. Jest powikłaniem nieleczonego zakażenia paciorkowcowego (np. anginy paciorkowcowej), które może prowadzić do bliznowacenia zastawki i jej sztywnienia.2910

Choroby zwyrodnieniowe zastawki

Zwapnienie zastawki aortalnej (calcific aortic valve disease) jest procesem związanym z wiekiem, w którym złogi wapnia odkładają się na zastawce aortalnej, powodując jej sztywnienie i zwężenie (stenozę). Z czasem może to również upośledzić zdolność zastawki do prawidłowego zamykania się, prowadząc do niedomykalności.11112

Zwyrodnienie śluzakowate (myxomatous degeneration) to proces, w którym tkanka zastawki staje się wiotka i może prowadzić do wypadania płatków zastawki i niedomykalności.1314

Choroby aorty

Patologie dotyczące aorty mogą również prowadzić do niedomykalności zastawki aortalnej, nawet przy braku pierwotnej patologii zastawki. Obejmują one:

Rozwarstwienie aorty (aortic dissection) – stan zagrażający życiu, w którym dochodzi do rozdarcia wewnętrznej warstwy aorty, co może wpływać na prawidłowe funkcjonowanie zastawki aortalnej poprzez różne mechanizmy: rozszerzenie zatok aorty, zaburzenie podpory płatków zastawki, bezpośrednie uszkodzenie płatka lub wypadanie płata rozwarstwienia przez zastawkę.2811

Poszerzenie aorty wstępującej (aortic root dilation) – może być idiopatyczne lub związane z chorobami, takimi jak zespół Marfana, zespół Ehlersa-Danlosa, nadciśnienie tętnicze czy zapalenie aorty. Poszerzenie aorty powoduje rozciągnięcie pierścienia zastawki, co uniemożliwia prawidłowe zamykanie się płatków.15166

Choroby tkanki łącznej

Niektóre choroby tkanki łącznej mogą prowadzić do niedomykalności zastawki aortalnej, często poprzez wpływ na aortę lub bezpośrednio na zastawkę:

  • Zespół Marfana – zaburzenie genetyczne tkanki łącznej, które może powodować poszerzenie aorty i niedomykalność zastawki aortalnej2916
  • Zespół Ehlersa-Danlosa – grupa zaburzeń tkanki łącznej, które mogą wpływać na strukturę zastawki aortalnej i aorty1314
  • Osteogenesis imperfecta (wrodzona łamliwość kości) – może również przyczyniać się do niedomykalności zastawki aortalnej15

Choroby reumatologiczne

Różne choroby reumatologiczne mogą być związane z niedomykalnością zastawki aortalnej:

  • Zesztywniające zapalenie stawów kręgosłupa (ankylosing spondylitis) – często powoduje zapalenie aorty (aortitis), które najczęściej obejmuje korzeń aorty, z towarzyszącą niedomykalnością zastawki aortalnej29
  • Toczeń rumieniowaty układowy (systemic lupus erythematosus) – może prowadzić do uszkodzenia zastawki aortalnej217
  • Reumatoidalne zapalenie stawów (rheumatoid arthritis)1418
  • Zespół Reitera (reactive arthritis)2
  • Choroba Behçeta14

Choroby infekcyjne

Oprócz infekcyjnego zapalenia wsierdzia i gorączki reumatycznej, inne infekcje mogą prowadzić do niedomykalności zastawki aortalnej:

  • Kiła (syphilis) – nieleczona kiła może prowadzić do zapalenia aorty (aortitis syphilitica), powodując uszkodzenie zastawki aortalnej219
  • Choroba Whipple’a – rzadka choroba bakteryjna, która może wpływać na serce i zastawki17

Uraz i jatrogeniczne przyczyny niedomykalności

Uraz klatki piersiowej może prowadzić do bezpośredniego uszkodzenia zastawki aortalnej lub aorty w pobliżu zastawki, powodując niedomykalność.202122

Do jatrogenicznych przyczyn niedomykalności zastawki aortalnej należą:

  • Powikłania przezcewnikowej implantacji zastawki aortalnej (TAVI/TAVR)36
  • Powikłania po balonowej walwuloplastyce aortalnej1417
  • Dysfunkcja protezy zastawkowej lub jej przeciek okołozastawkowy1711

Inne przyczyny

Istnieją również inne, rzadsze przyczyny niedomykalności zastawki aortalnej:

  • Nadciśnienie tętnicze – długotrwałe, niekontrolowane nadciśnienie może prowadzić do poszerzenia aorty i pierścienia zastawki aortalnej2324
  • Choroba Crohna1725
  • Zespół Turnera17
  • Olbrzymiokomórkowe zapalenie tętnic (giant cell arteritis)2318
  • Choroba Takayasu (Takayasu arteritis)9
  • Niektóre leki – szczególnie leki wspomagające odchudzanie, takie jak fenfluramina i deksfenfluramina (znane jako Fen-Fen)926
  • Agonisty dopaminy – np. bromokryptyna25

Różnice między ostrą i przewlekłą niedomykalnością zastawki aortalnej

Niedomykalność zastawki aortalnej można podzielić na ostrą i przewlekłą, różniące się etiologią, patofizjologią i manifestacją kliniczną.14

Ostra niedomykalność zastawki aortalnej

Główne przyczyny ostrej niedomykalności zastawki aortalnej obejmują:

  • Infekcyjne zapalenie wsierdzia – prowadzi do zniszczenia zastawki i perforacji płatków81421
  • Rozwarstwienie aorty – może powodować niedomykalność poprzez różne mechanizmy wymienione wcześniej86
  • Uraz klatki piersiowej – może prowadzić do uszkodzenia zastawki lub aorty2111
  • Dysfunkcja protezy zastawkowej1711

Przewlekła niedomykalność zastawki aortalnej

Przewlekła niedomykalność zastawki aortalnej rozwija się stopniowo przez wiele lat. Najczęstsze przyczyny to:

  • Wrodzone wady zastawki – szczególnie dwupłatkowa zastawka aortalna427
  • Zwyrodnienie zastawki związane z wiekiem1122
  • Poszerzenie aorty – z różnych przyczyn, w tym idiopatyczne, związane z nadciśnieniem tętniczym lub chorobami tkanki łącznej1628
  • Gorączka reumatyczna – rzadziej w krajach rozwiniętych10
  • Choroby reumatologiczne i tkanki łącznej1718

Zmiany patofizjologiczne w niedomykalności zastawki aortalnej

Patofizjologia niedomykalności zastawki aortalnej obejmuje złożone mechanizmy przebudowy dotyczące zastawki i okolicznych struktur.429

W niedomykalności zastawki aortalnej, krew przepływa wstecznie z aorty do lewej komory serca podczas rozkurczu. Prowadzi to do przeciążenia objętościowego lewej komory, która musi wyrzucić większą objętość krwi podczas każdego skurczu – zarówno normalną objętość wyrzutową, jak i objętość krwi, która wróciła podczas rozkurczu.129

W ostrej niedomykalności zastawki aortalnej dochodzi do nagłego wzrostu ciśnienia końcoworozkurczowego w lewej komorze i ciśnienia w lewym przedsionku, co może prowadzić do ostrej niewydolności serca, ponieważ serce nie ma czasu na adaptację.2930

W przewlekłej niedomykalności zastawki aortalnej, lewa komora powoli adaptuje się poprzez poszerzenie i przerost, co pozwala na pomieszczenie większej objętości krwi bez znacznego wzrostu ciśnienia końcoworozkurczowego. Z czasem jednak ta adaptacja może zawieść, prowadząc do niewydolności lewej komory.294

Na poziomie molekularnym, niedomykalność zastawki aortalnej wiąże się z aktywacją różnych szlaków genomowych i proteomicznych, które przyczyniają się do dysfunkcji zastawki, takich jak procesy prowadzące do jej zwapnienia czy zwyrodnienia śluzakowatego.4

Czynniki ryzyka niedomykalności zastawki aortalnej

Rozpoznanie czynników ryzyka niedomykalności zastawki aortalnej jest istotne dla wczesnej identyfikacji osób zagrożonych i potencjalnej profilaktyki. Główne czynniki ryzyka obejmują:3132

  • Wiek – ryzyko niedomykalności zastawki aortalnej wzrasta z wiekiem, zwłaszcza w przypadku zwyrodnieniowych zmian zastawki3233
  • Nadciśnienie tętnicze – szczególnie niekontrolowane, może prowadzić do poszerzenia aorty i niedomykalności zastawki3433
  • Wrodzone wady serca – zwłaszcza dwupłatkowa zastawka aortalna3235
  • Choroby tkanki łącznej – takie jak zespół Marfana, zespół Ehlersa-Danlosa3432
  • Inne choroby zastawek serca – np. zwężenie zastawki aortalnej32
  • Wywiad rodzinny – niedomykalność zastawki aortalnej lub tętniak aorty w rodzinie32
  • Przebyte infekcje – szczególnie takie, które mogą wpływać na zdrowie serca, jak gorączka reumatyczna czy infekcyjne zapalenie wsierdzia32
  • Płeć męska – niedomykalność zastawki aortalnej jest częstsza u mężczyzn w wieku 30-60 lat2

Różnice geograficzne i demograficzne w etiologii

Etiologia niedomykalności zastawki aortalnej wykazuje znaczące różnice geograficzne i demograficzne:1036

  • W krajach rozwiniętych (np. Stany Zjednoczone, Europa Zachodnia) najczęstszymi przyczynami są:
    • Dwupłatkowa zastawka aortalna36
    • Zwyrodnienie zastawki związane z wiekiem10
    • Poszerzenie aorty15
  • W krajach rozwijających się najczęstszą przyczyną pozostaje:
    • Gorączka reumatyczna1036
    • Kiła nieleczona odpowiednio10

Te różnice wynikają głównie z dostępności antybiotyków i opieki medycznej w poszczególnych regionach świata.10

Podsumowanie najczęstszych przyczyn

Podsumowując, najczęstsze przyczyny niedomykalności zastawki aortalnej to:41036

Ostre niedomykalności zastawki aortalnej:

  • Infekcyjne zapalenie wsierdzia1437
  • Rozwarstwienie aorty37
  • Uraz klatki piersiowej21

Przewlekłej niedomykalności zastawki aortalnej:

  • Dwupłatkowa zastawka aortalna (najczęstsza wrodzona przyczyna)436
  • Zwyrodnienie zastawki związane z wiekiem10
  • Poszerzenie aorty (z różnych przyczyn)15
  • Gorączka reumatyczna (głównie w krajach rozwijających się)36

Zrozumienie złożonej etiologii niedomykalności zastawki aortalnej jest kluczowe dla właściwego postępowania diagnostycznego i terapeutycznego, a także dla opracowania strategii profilaktycznych dla osób z grupy ryzyka.432

    https://www.mayoclinic.org/diseases-conditions/aortic-valve-regurgitation/symptoms-causes/syc-20353129
    In aortic valve regurgitation, the aortic valve doesn’t close properly. This causes blood to flow backward from the body’s main artery, called the aorta, into the lower left heart chamber, called the left ventricle. […] Aortic valve regurgitation can develop suddenly or over many years. Once the condition becomes severe, surgery often is needed to repair or replace the valve. […] Any condition that damages the aortic valve can cause aortic valve regurgitation. Causes may include: […] Heart valve disease present at birth. Some people are born with an aortic valve that has only two cusps, called a bicuspid valve. […] Narrowing of the aortic valve, called aortic stenosis. Calcium deposits can build up on the aortic valve as you age. […] Inflammation of the inner lining of the heart’s chambers and valves. This life-threatening condition also is called endocarditis.

    https://www.mountsinai.org/health-library/diseases-conditions/aortic-insufficiency
    Aortic regurgitation is a heart valve disease in which the aortic valve does not close tightly. This allows blood to flow from the aorta (the largest blood vessel) into the left ventricle (a chamber of the heart). […] Any condition that prevents the aortic valve from closing completely can cause this problem. When the valve does not close all the way, some blood comes back each time the heart beats. […] In the past, rheumatic fever was the main cause of aortic regurgitation. The use of antibiotics to treat strep infections has made rheumatic fever less common. Therefore, aortic regurgitation is more commonly due to other causes. These include: Ankylosing spondylitis, Aortic dissection, Congenital (present at birth) valve problems, such as bicuspid valve, Endocarditis (infection of the heart valves), High blood pressure, Marfan syndrome, Reiter syndrome (also known as reactive arthritis), Syphilis, Systemic lupus erythematosus, Trauma to the chest. […] Aortic insufficiency is most common in men between the ages of 30 and 60.
  • #3 Aortic Regurgitation: Background, Pathophysiology, Etiology
    https://emedicine.medscape.com/article/150490-overview
    The most common cause of chronic aortic regurgitation used to be rheumatic heart disease, but presently it is most commonly caused by bacterial endocarditis. […] In developed countries, it is caused by dilation of the ascending aorta (eg, aortic root disease, aortoannular ectasia). […] Acute aortic regurgitation may lead to destruction or perforation of the aortic valve leaflet due to infective endocarditis. […] Another cause of acute AR, chest trauma, may lead to a tear in the ascending aorta and disruption of the aortic valve support apparatus. […] With the development and clinical adoption of transcatheter aortic valve replacement (TAVR) techniques, post-TAVR AR has emerged as a common and potentially important cause of both acute and chronic AR. […] Bicuspid aortic valve is the most common congenital lesion of the human heart.

    https://pmc.ncbi.nlm.nih.gov/articles/PMC7288848/
    The most common causes of AI have been reported be congenital defects – especially bicuspid AV – and calcific AV disease. […] The diagnostic criteria for patients at risk for AI development is currently aimed at patients with prior anatomical valve abnormalities, such as congenital diseases, or prior heart diseases including AV sclerosis, rheumatic heart disease, and infective endocarditis. […] Given the wide array of genomic and proteomic pathways involved in AV dysregulation, it becomes clear that many more genes and proteins likely contribute to this process as well. […] Additionally, other proteins may contribute to other different pathological mechanisms implicated in AI development, such as myxomatous valve degeneration or calcification.
  • #4 Aortic Valve Regurgitation: Pathophysiology and Implications for Surgical Intervention in the Era of TAVR
    https://pmc.ncbi.nlm.nih.gov/articles/PMC7288848/
    Aortic insufficiency (AI) or regurgitation is caused by the malcoaptation of the aortic valve (AV) cusps due to intrinsic abnormalities of the valve itself, a dilatation or geometric distortion of the aortic root, or by some combination thereof. […] Traditional causes of AI include diseases such as rheumatic fever and endocarditis, congenital defects, cusp perforation, and degenerative processes. […] Recent close examination of such pathological processes has demonstrated a wide array of complex, active remodeling mechanisms affecting the valve and surrounding structures. […] New and ongoing research into the pathophysiology underlying these remodeling mechanisms has facilitated important discoveries pertaining to preventative, diagnostic, and mitigating strategies for patients with AI.
  • #5 Aortic Valve Regurgitation: Symptoms, Causes & Surgical Options
    https://www.heart-valve-surgery.com/aortic-valve-regurgitation-symptoms.php
    Aortic valve regurgitation can develop suddenly or over decades. It has a variety of causes, such as rheumatic fever or infection. […] Any condition that damages the aortic valve can cause regurgitation. Causes of aortic valve regurgitation may be: A congenital heart defect. You may have been born with an aortic valve that has one leaflet (unicuspid aortic valve) or two leaflets (bicuspid aortic valve) rather than the normal three leaflets. […] Rheumatic fever — a complication of strep throat and once a common childhood illness in the United States — can damage the aortic valve, leading to aortic valve regurgitation later in life. […] Other, rarer conditions that can damage the aortic valve and lead to regurgitation include Marfan syndrome (a disease of connective tissue), ankylosing spondylitis (a spine disorder) and syphilis (a sexually transmitted disease). Damage to the aorta near the site of the aortic valve, such as damage from trauma to your chest or from a tear in the aorta, also can cause backward flow of blood through the valve.
  • #6 Aortic valve regurgitation | Radiology Reference Article | Radiopaedia.org
    https://radiopaedia.org/articles/aortic-valve-regurgitation?lang=us
    Aortic regurgitation can be caused by root disease or intrinsic valvulopathy, although there is overlap. […] Predisposing factors or causes of chronic aortic regurgitation can broadly be divided into being due to root disease or due to intrinsic valvulopathy, although there is overlap. […] Root disease includes hypertension, congenital bicuspid aortic valve, connective tissue disorders (e.g. Marfan syndrome, Ehlers-Danlos syndrome, osteogenesis imperfecta, etc.), aortic dissection, Takayasu arteritis, syphilitic aortitis, etc. […] Valvular causes include rheumatic heart disease, calcific aortic valve disease (i.e. calcific aortic stenosis), bacterial infective endocarditis, prolapse, quadricuspid aortic valve, ankylosing spondylitis, syphilitic aortitis, radiation-induced heart disease, etc. […] Acute aortic regurgitation is less common, but also exists, with specific causes such as bacterial infective endocarditis, aortic dissection, traumatic rupture, and iatrogenic causes (e.g. during transcatheter aortic valve implantation).

It prevents the valve from opening properly. Aortic stenosis also may prevent the valve from closing properly.
  • #8 Acute aortic regurgitation in adults – UpToDate
    https://www.uptodate.com/contents/acute-aortic-regurgitation-in-adults
    Acute aortic regurgitation in adults […] ETIOLOGY […] The causes of acute AR with a native aortic valve are limited and include: […] ● Endocarditis – Endocarditis results in valve destruction and leaflet perforation. W dodatku, aortic perivalvular abscess may rupture into the left ventricle, resulting in AR, or into the left atrium or right ventricular outflow tract, with a clinical presentation that mimics acute AR. […] ● Aortic dissection – Aortic dissection can result in AR by four mechanisms: dilation of the sinuses with incomplete coaptation of the leaflets at the center of the valve; involvement of a valve commissure resulting in inadequate leaflet support; direct extension of the dissection into the base of a leaflet, resulting in a flail valve leaflet; and prolapse of the dissection flap across the aortic valve into the left ventricular outflow tract in diastole impeding leaflet closure. Patients with a bicuspid aortic valve are at higher risk of aortic dissection.
  • #9 Aortic Regurgitation: Background, Pathophysiology, Etiology
    https://emedicine.medscape.com/article/150490-overview
    Certain weight loss medications, such as fenfluramine and dexfenfluramine (commonly referred to as Phen-Fen), may induce degenerative valvular changes that result in chronic AR. […] Rheumatic fever, a common cause of AR in the first half of the 20th century, has become less common in the United States, although it remains prevalent in some immigrant populations. […] Ankylosing spondylitis often causes an aortitis, which most frequently involves the aortic root, with associated AR. […] Takayasu arteritis, in addition to having aortic valvular (and coronary) involvement, can produce an aortitis. […] Connective tissue disorders that can cause significant AR include Marfan syndrome, Ehlers-Danlos syndrome, floppy aortic valve, aortic valve prolapse, sinus of Valsalva aneurysm, and aortic annular fistula.
  • #10 Aortic Regurgitation – Heart and Blood Vessel Disorders – Merck Manual Consumer Version
    https://www.merckmanuals.com/home/heart-and-blood-vessel-disorders/heart-valve-disorders/aortic-regurgitation
    Aortic regurgitation is due to deterioration of the aortic valve and the surrounding aortic root (base of the aorta the blood vessel transporting blood from the heart to the rest of the body). […] The deterioration sometimes occurs in a person with a bicuspid aortic valve but may also result from a bacterial infection of the valve or rheumatic fever. […] The most common causes of acute aortic regurgitation are infection of the valve (infective endocarditis) and a tear in the lining of the aorta (aortic dissection). […] The most common causes of chronic aortic regurgitation are spontaneous weakening of the valve or the ascending aorta (particularly with a birth defect in which the aortic valve is bicuspid with only two, instead of three, cusps), rheumatic fever, and syphilis. […] Rheumatic fever and syphilis used to be the most common causes of aortic regurgitation in North America and Western Europe, where both disorders are now rare because of the widespread use of antibiotics. […] In regions where antibiotics are not widely used, aortic regurgitation due to rheumatic fever or syphilis is still common.

    Aortic valve regurgitation is a problem with the aortic valve. […] When you have aortic valve regurgitation, this valve doesn’t close as it should. […] Any condition that damages the aortic valve can cause aortic regurgitation. Causes of long-term aortic valve regurgitation include heart problems you’re born with, calcium buildup on the valve, and an enlarged aorta. […] Causes of sudden aortic valve regurgitation include endocarditis and trauma to the heart or aorta. […] Causes of chronic (long-term) valve problems include: Being born with a bicuspid aortic valve. Calcium buildup on the valve. Enlargement of the aorta. Rheumatic fever. […] Causes of sudden (acute) aortic valve regurgitation include: Endocarditis. This is an infection in the heart. Aortic dissection. This means that the inner layer of the aorta separates from the middle layer. Problems with a replacement aortic valve. Trauma to the heart valve or aorta.

    Aortic regurgitation is a heart disorder that leads to leaking in the aortic valve. […] Aortic valve regurgitation, also called aortic insufficiency, is a heart disorder where the aortic valve leaks. […] Causes of aortic valve regurgitation include: […] Some people are born with structural abnormalities in their aortic valve, such as bicuspid aortic valve. […] Endocarditis is an infection of the heart valves, typically caused by bacteria. […] This inflammatory condition can develop as a complication of untreated strep throat. […] Aortic dissection is a life-threatening condition where the aortas inner layer develops tearing, causing blood to flow between the layers of the aortic wall. […] These disorders can cause abnormalities in your bodys connective tissues, impairing the structure and functioning of the aorta and aortic valve. […] The aortic valve changes as we age, leading to calcification and thickening of the aortic valves leaflets. […] If you suffer blunt trauma or other serious injury to your chest, the aortic valve could be damaged.

  • #15 Aortic regurgitation – Wikipedia
    https://en.wikipedia.org/wiki/Aortic_regurgitation
    Aortic regurgitation is often due to the aortic root dilation (annuloaortic ectasia), which is idiopathic in over 80% of cases, but otherwise may result from aging, syphilitic aortitis, osteogenesis imperfecta, aortic dissection, Behet’s disease, reactive arthritis and systemic hypertension. […] Aortic root dilation is the most common cause of aortic regurgitation in developed countries. […] Additionally, aortic regurgitation has been linked to the use of some medications, specifically medications containing fenfluramine or dexfenfluramine isomers and dopamine agonists. […] Other potential causes that affect the valve directly include Marfan syndrome, Ehlers-Danlos syndrome, ankylosing spondylitis, and systemic lupus erythematosus. […] In acute cases of aortic regurgitation, the main causes are infective endocarditis, aortic dissection or trauma.

    https://www.escardio.org/Journals/E-Journal-of-Cardiology-Practice/Volume-18/chronic-aortic-regurgitation-diagnosis-and-therapy-in-the-modern-era
    Aortic regurgitation (AR, also termed aortic insufficiency) results in diastolic blood flow from the aorta back into the left ventricle (LV) and may be caused by a variety of acquired or congenital aetiologies preventing complete coaptation of the aortic valve (AV) leaflets (also called cusps). […] Primary (organic) AR is an intrinsic disease of the AV leaflets, whereas secondary (functional) AR results from distortion or dilation of the aortic root and/or ascending aorta leading to incomplete aortic leaflet coaptation. […] Some disease entities may cause AR by both mechanisms. For example, Marfans syndrome and bicuspid aortic valve (BAV) pathologies do affect the structure of the AV and may also cause dilatation of the aortic root and ascending aorta leading to a functionally regurgitant valve.

    Aortic regurgitation (AR), also known as aortic insufficiency, is a form of valvular heart disease that allows for the retrograde flow of blood back into the left ventricle. […] Typical etiologies responsible for acute AR include infective endocarditis, traumatic and non-traumatic rupture of the ascending aorta with aortic cusp prolapse, iatrogenic AR due to percutaneous aortic balloon valvuloplasty, prosthetic valve dysfunction, and perivalvular leak or dehiscence of a prosthetic valve. […] The etiologies responsible for chronic AR may be extensive, they include rheumatic heart disease (the most common cause in the developing world), infective endocarditis, myxomatous valve degeneration, congenital valve abnormalities (most commonly a bicuspid aortic valve while unicuspid and quadricuspid have also been reported), senile valvular calcifications, age-related dilatation of the aorta, ectasia of the aortic annulus, aortic dissection, aortitis/aortic root dilatation secondary to syphilis or giant cell arteritis, trauma, systemic hypertension, drug-induced valvulopathy, Whipple disease, osteogenesis imperfecta, and Crohn disease.

    https://emedicine.medscape.com/article/150490-overview
    Aortic regurgitation (AR) is the diastolic flow of blood from the aorta into the left ventricle (LV). Regurgitation is due to incompetence of the aortic valve or any disturbance of the valvular apparatus (eg, leaflets, annulus of the aorta) resulting in the diastolic flow of blood into the left ventricular chamber. […] Valvular abnormalities that may result in AR can be caused by the following: Congenital causes – Bicuspid aortic valve is the most common congenital cause. […] Acquired causes include rheumatic fever, infective endocarditis, collagen vascular diseases, degenerative aortic valve disease, traumatic causes, and postsurgical causes (including post-transcatheter aortic valve replacement). […] Abnormalities of the ascending aorta, in the absence of valve pathology, may also cause AR. Such abnormalities may occur with longstanding, uncontrolled hypertension, Marfan syndrome, idiopathic aortic dilation, cystic medial necrosis, senile aortic ectasia and dilation, syphilitic aortitis, giant cell arteritis, Takayasu arteritis, ankylosing spondylitis, Whipple disease, and other spondyloarthropathies.

    Aortic valve regurgitation is a condition that occurs when the heart’s aortic valve doesn’t close as tightly as it should. Whenever the aortic valve doesn’t close properly, blood leaks backward into the left ventricle, which is one of the chambers of your heart. That causes the heart to work overtime to compensate for the blood that has leaked into the left ventricle. As a result, you may feel short of breath or fatigued, and this condition could even lead to more serious problems like heart failure or an irregular heartbeat. […] There are several different causes of aortic valve regurgitation: Rheumatic fever – This is an inflammatory disease that can occur when strep throat or scarlet fever isn’t taken care of properly. This disease can cause a wide range of conditions that include aortic valve regurgitation. […] Infections – This is when inflammation of the inner lining of the heart’s chamber occurs.

    Aortic valve regurgitation, also called aortic valve insufficiency, occurs when the aortic valve doesn’t close properly, causing blood to flow back into the heart. This requires the heart to work harder. Over time, the condition causes the heart to stretch and enlarge and can lead to heart failure. Your chance of developing this condition increases with age. […] In the chronic form of aortic valve regurgitation, symptoms tend to build slowly over time. This may be caused by aging, being born with an abnormal aortic valve, childhood rheumatic fever, enlargement of the aorta resulting from high blood pressure, or atherosclerosis, a hardening of the arteries. […] Acute aortic valve regurgitation occurs suddenly, leading to shortness of breath and sometimes heart failure. It can be caused by an aortic dissection, which is a tear in the aortic wall; endocarditis, an infection of the heart; or trauma to the heart or aorta, such as from a car accident.

    Aortic regurgitation is a condition where the one-way aortic valve doesn’t close tightly and therefore becomes leaky. Blood exits the heart when the left ventricle (heart muscle) pumps. As the valve is leaky, when the heart relaxes blood is able to fall back into the heart. […] There are a number of causes of aortic regurgitation. It can be due to a problem with the valve or a problem with the aorta (main blood vessel leading away from the heart – if the aorta is stretched the valve leaflets are unable to close properly resulting in a leaky valve). Common causes are listed below: […] Valve related causes: Bicuspid aortic valve (congenital abnormality), Damage to the aortic valve following heart valve infection (endocarditis), Valve degeneration (age related wear and tear), Rheumatic fever. […] Aorta-related causes: Longstanding hypertension (high blood pressure), Diseases affecting the elastic tissue of the arteries (e.g. Marfan’s syndrome, Ehlers Danlos), Idiopathic dilatation (unexplained stretching of the aorta).

    https://cvphysiology.com/heart-disease/hd005
    Aortic regurgitation occurs when the aortic valve cannot close completely and blood flows back from the aorta (Ao) into the left ventricle after ejection into the aorta is complete. […] A defining characteristic of aortic regurgitation is an increase in aortic pulse pressure (systolic minus diastolic pressure). […] The backward flow of blood into the ventricular chamber during diastole results in a diastolic murmur. […] Early in the course of regurgitant aortic valve disease, there is a large increase in left ventricular end-diastolic pressure and left atrial pressure. […] With long-standing regurgitation and volume overload of the chambers, the ventricle and atria dilate anatomically, which attenuates the increase in end-diastolic pressure caused by the increased end-diastolic volume.

    Aortic regurgitation can have many causes, including diseases that affect connective tissue, which is the substance of the aortic valve and the ascending aorta. […] In chronic aortic regurgitation, valvular surgery is needed when the regurgitant volume becomes moderate to severe. However, certain etiologies may dictate surgery even if the degree of regurgitation is mild. For instance, the patient with aortic regurgitation resulting from dissection of the ascending aorta requires immediate surgery to repair the dissection. […] A few diseases can cause sudden severe aortic regurgitation. In these diseases, the clinical picture of acute aortic regurgitation results from a sudden and marked increase in diastolic filling volume, with no chance for the left ventricle or the stiff pericardium to accommodate this increase.

    Aortic regurgitation (AR) is a valvular heart disease characterized by incomplete closure of the aortic valve leading to the reflux of blood from the aorta into the left ventricle (LV) during diastole. Aortic regurgitation can be acute (primarily caused by bacterial endocarditis or aortic dissection) or chronic (e.g., due to a congenital bicuspid valve or rheumatic fever) and may be caused by a valvular defect or an abnormality of the aorta. […] Acute aortic regurgitation can be caused by infective endocarditis, aortic dissection (ascending aorta), chest trauma, and iatrogenic complications. […] Chronic aortic regurgitation can be caused by primary valvular defects such as congenital bicuspid aortic valve, calcific aortic valve disease, and rheumatic heart disease, as well as aortic dilatation due to connective tissue disorders, chronic hypertension, aortitis of any etiology, and thoracic aortic aneurysm.
