Zwężenie zastawki aorty
Epidemiologia

Zwężenie zastawki aorty (AS) jest najczęstszą wadą zastawkową serca w krajach rozwiniętych, z częstością występowania rosnącą wraz z wiekiem: 1-2% u osób >65 lat, 2-3,4% u >75 lat oraz 4-9,8% u >85 lat. Ciężkie AS dotyczy około 3,4% osób powyżej 75 roku życia. Dominującą etiologią w krajach wysoko rozwiniętych jest zwyrodnieniowo-wapniejące zwężenie (81,9%), z mniejszym udziałem etiologii reumatycznej (11,2%) i wrodzonej (5,6%). Wapniejące AS występuje częściej u mężczyzn (4:1), natomiast u kobiet diagnoza często jest opóźniona, co wiąże się z większym ryzykiem powikłań, w tym niewydolności nerek i zespołu kruchości. Czynniki ryzyka obejmują m.in. podwyższony poziom lipoproteiny(a), nadciśnienie tętnicze, przewlekłą chorobę nerek, cukrzycę, hipercholesterolemię, palenie tytoniu oraz wiek. Wysoka częstość współwystępowania AS u pacjentów dializowanych (17,5% zwężenia) podkreśla potrzebę szczególnej uwagi w tej grupie.

Epidemiologia zwężenia zastawki aorty

Zwężenie zastawki aorty (AS) jest najczęstszą wadą zastawkową serca w krajach rozwiniętych, stanowiąc istotne obciążenie dla systemów opieki zdrowotnej, szczególnie w starzejących się populacjach. Częstość występowania tej choroby znacząco wzrasta wraz z wiekiem, co w obliczu wydłużania się średniej długości życia prowadzi do zwiększenia liczby przypadków wymagających interwencji medycznej.12

Częstotliwość występowania w różnych grupach wiekowych

Badania epidemiologiczne wykazują wyraźny wzrost częstości występowania zwężenia zastawki aorty wraz z wiekiem:3

  • W populacji osób powyżej 65 roku życia: około 1-2%45
  • U osób powyżej 75 roku życia: 2-3,4%67
  • W grupie wiekowej powyżej 85 roku życia: 4-9,8%89

Szczególnie istotne są dane wskazujące, że u osób powyżej 75 roku życia częstość występowania ciężkiego zwężenia zastawki aorty wynosi około 3,4%.10 W populacji australijskiej szacuje się, że ciężkie zwężenie zastawki aorty występuje u 1,5% osób powyżej 55 roku życia i 3,5% u osób powyżej 75 roku życia, z roczną zapadalnością wynoszącą 1,8 na 1000 osób.11

Różnice geograficzne w występowaniu zwężenia zastawki aorty

Istnieją znaczące różnice w epidemiologii zwężenia zastawki aorty między krajami wysoko i nisko rozwiniętymi. W Ameryce Północnej i Europie dominuje zwyrodnieniowo-wapniejące zwężenie zastawki aorty, podczas gdy w krajach rozwijających się częściej występuje choroba reumatyczna zastawek.1213

Według danych z Euro Heart Survey dotyczącego chorób zastawkowych, etiologia zwężenia zastawki aorty w krajach rozwiniętych to:1415

  • Degeneracyjno-wapniejąca: 81,9% przypadków
  • Reumatyczna: 11,2% przypadków
  • Wrodzona: 5,6% przypadków
  • Pozapalna (po zapaleniu wsierdzia): 1,3% przypadków

Różnice między płciami

Badania epidemiologiczne wskazują na równy odsetek zwężenia zastawki aorty wśród mężczyzn i kobiet, jednak istnieją istotne różnice między płciami w przebiegu choroby.16 Wapniejące zwyrodnieniowe zwężenie zastawki aorty występuje częściej u mężczyzn, z proporcją mężczyźni:kobiety wynoszącą 4:1.1718

Zwężenie zastawki aorty u kobiet często jest diagnozowane późno w przebiegu choroby, z większym ryzykiem powikłań, takich jak zaawansowany wiek, większe obciążenie objawami, zespół kruchości, niewydolność nerek i wyższy wskaźnik objawowej niewydolności serca.19 Jednym z potencjalnych powodów tego opóźnionego rozpoznania jest niższa świadomość choroby i mniejsza liczba skierowań do specjalistów w porównaniu z pacjentami płci męskiej.20

Prognozy i obciążenie systemów opieki zdrowotnej

Prognozy w krajach wysoko rozwiniętych jednoznacznie przewidują wzrost obciążenia związanego ze zwężeniem zastawki aorty.21 Wysoka częstość występowania czynników ryzyka zwężenia zastawki aorty, takich jak nadciśnienie tętnicze oraz wydłużanie się oczekiwanej długości życia, oznaczają, że w przyszłości prawdopodobnie wystąpi znaczne obciążenie związane z tą chorobą również w krajach o niższych dochodach.22

Standaryzowana wiekowo częstość występowania wapniejącej choroby zastawki aortalnej wynosiła 116,3 przypadków na 100 000 osób w 2019 roku, co oznacza ponad dwukrotny wzrost od 1990 roku.23 Liczba przypadków w Stanach Zjednoczonych i Europie ma według prognoz wzrosnąć dwu- lub trzykrotnie w najbliższych dekadach ze względu na starzenie się populacji.24

Współwystępowanie chorób i czynniki ryzyka

Zwężenie zastawki aorty często współwystępuje z innymi chorobami. Szczególnie wysoka częstość występowania zwapnień zastawki aorty jest obserwowana u pacjentów z schyłkową niewydolnością nerek i dializowanych.25 W badaniu obejmującym 155 pacjentów hemodializowanych, pewien stopień sklerotyzacji zastawki aorty stwierdzono u 66,5%, zwężenie zastawki aorty u 17,5%, a tylko 16% badanych miało prawidłową zastawkę aortalną.26

Do głównych czynników ryzyka rozwoju zwężenia zastawki aorty należą:272829

  • Podwyższony poziom lipoproteiny(a)
  • Nadciśnienie tętnicze
  • Przewlekła choroba nerek
  • Cukrzyca
  • Podwyższony wskaźnik masy ciała (BMI)
  • Wiek
  • Płeć męska
  • Hiperlipidemia
  • Palenie tytoniu

Nadzór i monitorowanie zwężenia zastawki aorty

Skuteczne systemy nadzoru nad pacjentami z zwężeniem zastawki aorty mają kluczowe znaczenie dla optymalnego leczenia tej choroby.30 Utworzenie krajowych programów nadzoru nad zwężeniem zastawki aorty może przynieść znaczące korzyści zarówno dla pacjentów, jak i dla systemów opieki zdrowotnej, poprawiając jakość i spójność monitorowania oraz zwalniając zasoby na przyjmowanie nowych pacjentów.31

Zalecenia dotyczące nadzoru klinicznego

Obecne wytyczne zalecają różne częstotliwości badań kontrolnych w zależności od stopnia zwężenia zastawki aorty:3233

  • Łagodne zwężenie zastawki aorty: badanie echokardiograficzne co 3-5 lat
  • Umiarkowane zwężenie zastawki aorty: badanie echokardiograficzne co 1-2 lata
  • Ciężkie zwężenie zastawki aorty bez objawów: badanie echokardiograficzne co 6-12 miesięcy

W przypadku pacjentów z bezobjawowym ciężkim zwężeniem zastawki aorty i prawidłową funkcją skurczową zaleca się ponowną ocenę co 6 miesięcy, ponieważ 3-6% z nich będzie rozwijać objawy lub zaburzenia frakcji wyrzutowej lewej komory każdego roku.34

U pacjentów z dwupłatkową zastawką aortalną (BAV) wytyczne zalecają seryjne oceny aorty za pomocą echokardiografii przezklatkowej (TTE) w odstępach dostosowanych do obecności i nasilenia poszerzenia aorty.35

Wyzwania w nadzorze klinicznym

Pomimo istniejących wytycznych, nadzór nad pacjentami z zwężeniem zastawki aorty często bywa niejednolity, a obrazowanie kontrolne może być rzadsze niż zalecane.36 Ta luka w jakości opieki wskazuje na znaczenie interdyscyplinarnej komunikacji między kardiologią, radiologią i kardiochirurgią.37

Istnieje pilna potrzeba systematycznego nadzoru i wdrożenia mechanizmów klinicznej obserwacji w celu monitorowania populacji pacjentów ze zwiększonym ryzykiem postępującej choroby zastawkowej i aortopatii.38

Nowe trendy w podejściu do zwężenia zastawki aorty

Ostatnie badania podważają tradycyjne podejście „czekaj i obserwuj” w przypadku bezobjawowego ciężkiego zwężenia zastawki aorty, ponieważ dowody sugerują, że może to prowadzić do długoterminowej chorobowości i przedwczesnej śmierci, nawet po wymianie zastawki.39

Wczesna interwencja vs obserwacja kliniczna

Badanie EARLY TAVR wykazało, że przezcewnikowa wymiana zastawki aortalnej (TAVR) w przypadku bezobjawowego ciężkiego zwężenia zastawki aorty przynosi korzyści w porównaniu z nadzorem klinicznym.40 Podczas mediany obserwacji wynoszącej 3,8 roku, pierwszorzędowy punkt końcowy obejmujący zgon, udar mózgu lub nieplanowaną hospitalizację z przyczyn sercowo-naczyniowych wystąpił u 26,8% pacjentów w grupie TAVR i 45,3% pacjentów w grupie obserwacji klinicznej.41

Metaanaliza randomizowanych badań klinicznych porównujących wczesną wymianę zastawki aortalnej (AVR) z obserwacją kliniczną u pacjentów z bezobjawowym ciężkim zwężeniem zastawki aorty wykazała, że wczesna AVR była związana ze znacznym zmniejszeniem liczby nieplanowanych hospitalizacji z powodu chorób sercowo-naczyniowych lub niewydolności serca (14,6% vs 31,9%; HR: 0,40; 95% CI: 0,30-0,53; P<0,01) oraz udaru mózgu (4,5% vs 7,2%; HR: 0,62; 95% CI: 0,40-0,97; P=0,03).42

Wyniki dla różnych grup wiekowych

Analiza z badania EARLY TAVR wykazała, że pacjenci w wieku 65-69 lat, którzy przeszli wczesne TAVR, odnieśli największe korzyści, ze znacznym zmniejszeniem ryzyka udaru mózgu (0% przy wczesnym TAVR vs 13% przy obserwacji klinicznej) i sześciokrotnie niższym wskaźnikiem zgonu, udaru mózgu lub hospitalizacji z powodu niewydolności serca w porównaniu z tymi, którzy przeszli obserwację kliniczną (4,7% vs 25,6%) w okresie do pięciu lat po zabiegu.4344

Biorąc pod uwagę korzyści i brak ryzyka u pacjentów w wieku 65 lat lub starszych, wczesne TAVR powinno być preferowane w stosunku do obserwacji klinicznej we wszystkich grupach wiekowych.45

Nowe podejście do umiarkowanego zwężenia zastawki aorty

Coraz więcej dowodów wskazuje, że umiarkowane zwężenie zastawki aorty ma gorsze rokowanie niż wcześniej sądzono, z wyraźnym zwiększonym ryzykiem niewydolności serca, śmiertelności z przyczyn sercowo-naczyniowych i śmiertelności ogólnej.46 Pacjenci, którzy przeszli wymianę zastawki aortalnej (AVR) z powodu umiarkowanego zwężenia zastawki aorty, mieli lepsze wyniki niż porównywalni pacjenci leczeni obserwacją kliniczną, ze znaczną poprawą przeżycia i przebudowy lewej komory w czasie wieloletniej obserwacji.47

W analizie wielozmiennej skorygowanej, pacjenci po AVR mieli znacząco wyższą frakcję wyrzutową lewej komory (LVEF) i niższe ciśnienie skurczowe w prawej komorze w czasie niż pacjenci leczeni obserwacją kliniczną, u których oba te parametry pogorszyły się w okresie badania.48

Zarówno grupy TAVR, jak i chirurgicznej wymiany zastawki aortalnej (SAVR) wykazały znaczące korzyści w porównaniu z obserwacją kliniczną.49

Przyszłe kierunki w nadzorze nad zwężeniem zastawki aorty

W obliczu rosnącej częstości występowania zwężenia zastawki aorty i zwiększającej się liczby pacjentów wymagających interwencji, istnieje pilna potrzeba opracowania skuteczniejszych strategii nadzoru i wcześniejszego leczenia.50

Rola wielomodalnego obrazowania kardiologicznego

Wielomodalny podejście do obrazowania kardiologicznego (MCI) odgrywa kluczową rolę w ocenie zwężenia zastawki aorty.51 Dodanie uzupełniających technik, takich jak echokardiografia przezprzełykowa (TEE), wielorzędowa tomografia komputerowa (MDCT) i rezonans magnetyczny serca (CMR), pozwala na właściwą klasyfikację w większości przypadków.52

W wielu przypadkach ciężkie zwężenie zastawki aorty nie jest prostą diagnozą. W tych trudnych scenariuszach wielomodalne obrazowanie kardiologiczne może prowadzić do bardziej precyzyjnej klasyfikacji i lepszego procesu podejmowania decyzji.53

Potrzeba zmian w wytycznych klinicznych

Istnieje pilna potrzeba zmiany praktyki i wytycznych TAVR w leczeniu pacjentów ze zwężeniem zastawki aorty, które obecnie zalecają „czujne oczekiwanie” do czasu pojawienia się objawów.5455 Jak wykazano w badaniu EARLY TAVR, pacjenci początkowo określani jako bezobjawowi stawali się objawowi w nagły i nieprzewidywalny sposób, podkreślając znaczenie wczesnej oceny przez zespół kardiologiczny w celu poprawy wyników leczenia pacjentów i korzyści dla systemu opieki zdrowotnej.56

Badanie EARLY TAVR daje mocne podstawy do zmiany paradygmatu w kierunku wczesnej interwencji, szczególnie u pacjentów bezobjawowych z ciężkim zwężeniem zastawki aorty.57

Poprawa świadomości i dostępności leczenia

Konieczne jest zwiększenie świadomości wśród lekarzy na temat różnic między płciami w leczeniu ciężkiego zwężenia zastawki aorty, aby zlikwidować obecną lukę w opiece zdrowotnej między płciami.58 Lekarze pierwszego kontaktu odgrywają kluczową rolę w identyfikacji pacjentów z ciężkim zwężeniem zastawki aorty i ułatwieniu szybkiej diagnozy i leczenia.59

Program poprawy jakości Target: Aortic Stenosis ma na celu poprawę doświadczenia pacjenta od wystąpienia objawów do odpowiedniej diagnozy i dalszego postępowania, aż do terminowego leczenia i zarządzania chorobą.60 Opóźnienie w skierowaniu bezpośrednio wpływa na wskaźniki przeżywalności.61

Biorąc pod uwagę rosnącą częstość występowania ciężkiego zwężenia zastawki aorty i jego wpływ na chorobowość i śmiertelność, skuteczny nadzór epidemiologiczny i kliniczny staje się coraz ważniejszy dla optymalizacji wyników leczenia pacjentów i efektywnego wykorzystania zasobów opieki zdrowotnej.62

    https://pmc.ncbi.nlm.nih.gov/articles/PMC2999052/
    Aortic stenosis (AS) is the most common valvular heart disease in the world. It is a disease of the elderly and as our population is getting older in both the developed and the developing world, there has been an increase in the prevalence of AS. It is impacting the mortality and morbidity of our elderly population. It is also causing a huge burden on the healthcare system. […] The prevalence of AS increases from 2% in adults over 65 years to 4% in adults over 85 years of age. AS is a progressive condition and after the onset of heart failure, survival is 2 years without valve replacement. 50% of patients with AS presenting with angina, syncope or heart failure survive for 5, 3 or 2 years respectively without aortic valve replacement (AVR). As life spans increase, the burden of senile AS on the health care system is expected to increase. Close monitoring and use of AVR when the disease becomes significant remains the standard of care. AS is the most common reason for AVR in the developed world.

    Aortic stenosis is the most common valvulopathy, present in up to one-quarter of all patients with chronic valvular heart disease 1,2. The condition has a male predilection in a 4:1 ratio 1, and the incidence of degenerative aortic valve disease, the most common etiology of aortic stenosis, is increasing 1,2. […] The decision to treat aortic stenosis is based on the severity 1,2. Management involves a combination of lifestyle and pharmacotherapy measures (a similar armamentarium to that used in heart failure), balloon valvuloplasty, and aortic valve replacement 1,2.

    This review aims to update healthcare providers on contemporary diagnostic and treatment information pertaining to aortic stenosis. […] The prevalence of aortic stenosis continues to increase, and so does the burden of treatable disease. This has important implications for healthcare systems and the economy. […] The global prevalence of AS continues to steadily increase. […] The age-standardized prevalence of calcific aortic valve disease was 116.3 cases per 100,000 people in 2019, more than doubling since 1990. […] AS is particularly prevalent in high-income countries, partly driven by its strong correlation with age; pooled meta-data suggest contemporary prevalence exceeds 10% in the population aged over 75 years. […] This creates significant challenges for healthcare infrastructure and resource allocation, given the growing treatable burden of disease.

    Objective To assess prevalence, incidence, prognosis and progression of degenerative valvular aortic stenosis (AS). […] Prevalence studies have been conducted previously, and several authors have investigated the prognosis and progression of clinical AS, but to our knowledge there are no population-based incidence studies or progression studies available. […] The results of the prevalence calculations both for the surveys and after inclusion of hospital data are displayed in table 2. At all three time points we consistently found an increase in prevalence with age, weighted mean values in the combined survey T4/5/6 and hospital data being 0.2% (95% CI 0% to 0.4%) in the 50-59 year cohort, 1.3% (95% CI 0.9% to 1.7%) in the 60-69 year cohort, 3.9% (95% CI 3.2% to 4.6%) in the 70-79 year cohort and 9.8% (95% CI 7.8% to 11.8%) in the 80-89 year cohort. Thus, the prevalence increases exponentially with age.

  • #27 Risk factors for aortic stenosis
    https://www.escardio.org/Journals/E-Journal-of-Cardiology-Practice/Volume-18/risk-factors-for-aortic-stenosis
    Although aortic valve stenosis (AVS) shares several risk factors with atherosclerosis, lipid-lowering therapy does not reduce AVS progression. Elevated lipoprotein(a), hypertension, chronic kidney disease, and diabetes all increase the risk of AVS. In addition, recent studies have emphasised increased body mass index (BMI) as a particularly strong AVS risk factor. Modifying risk factors for AVS may reduce morbidity and potentially avoid valve interventions with health economic benefits. […] The increased prevalence of non-rheumatic aortic valve disease parallels an increasingly ageing population. Degenerative AVS is the most common valvular heart disease and develops from fibrocalcific changes of the aortic valve cusps, resulting in reduced valve opening and eventually haemodynamic obstruction of the left ventricular outflow.

    Assessing the association of traditional cardiovascular risk factors with incident aortic valve disease is therefore important in order to identify potential preventive strategies in valvular heart disease. Identifying key risk factors for AVS may, in addition, provide clues for risk stratification and future interventional trials to slow down AVS progression and to avoid, or at least postpone, aortic valve interventions. […] Hypertension is present in 21% of those with AVS, and 1.1% of hypertensive subjects have AVS. However, only a few longitudinal studies have evaluated the association of hypertension with incident AVS. A recent cohort study of 5.4 million subjects followed for a median of 9.2 years through UK electronic healthcare records showed that elevated systolic blood pressure increased the risk of both AVS and AR with approximately 40% for each incremental 20 mmHg.

    A database study of serum creatinine measures from 1.1 million subjects revealed that decreased glomerular filtration rate (GFR) was associated with an increased risk of incident AVS. Compared with reference (GFR 90 ml/min/1.73 m2), even a slight decrease in kidney function (GFR 60-90) was associated with a 14% higher risk of developing AVS. This risk increased with decreasing kidney function reaching a 56% increased risk of incident AVS in subjects with a GFR 30. […] Type 2 diabetes mellitus (T2DM) was associated with an increased incident AVS in retrospective studies. Given the close connection between cardiometabolic risk factors, it is also important that obesity is taken into consideration as a possible confounder for the relationship between T2DM and AVS. […] There is an urgent need for prospectively evaluating the effects of risk modifications as well as treatments targeting the potential AVS risk factors. Examples of such therapeutic strategies could potentially include weight loss, Lp(a) lowering, smoking cessation, as well as antihypertensive and antidiabetic treatments. Deciphering the risk factors contributing to AVS incidence and progression will be key in designing preventive measures for slowing down AVS progression, and eventually preventing, or at least postponing, AVS interventions.

    Non-rheumatic aortic stenosis (AS) is among the most common valvular diseases in the developed world. Current guidelines support aortic valve replacement (AVR) for severe symptomatic AS, which carries high morbidity and mortality when left untreated. […] In contrast, moderate AS has historically been thought to be a benign diagnosis for which the potential benefits of AVR are outweighed by the procedural risks. However, emerging data demonstrating the substantial mortality risk in untreated moderate AS and substantial improvements in periprocedural and perioperative mortality with AVR have challenged the traditional risk/benefit paradigm. […] The prevalence of AS increases with age, with about 12.4% of adults over age 75 with mild, moderate or severe AS. […] Current guidelines account for the crescendo progression pattern of AS by recommending more frequent surveillance echocardiograms when the disease progresses from mild to moderate (from every 3-5 years to every 1-2 years).

    Symptomatic aortic stenosis (AS) is a class I indication for aortic valve replacement. Severe asymptomatic AS, however, has traditionally been managed conservatively using an expectant approach. […] Recent studies have raised concerns about this watchful waiting strategy because evidence suggests that it may lead to long-term morbidity and premature death, even after valve replacement. […] Asymptomatic severe AS is a common condition affecting older adults and carries a substantial risk of progression to severe disease over time. Current guidelines recommend a strategy of expectant management until symptoms or LV dysfunction develop, but recent evidence challenges this approach. […] The findings from recent trials, such as RECOVERY and AVATAR, have provided support for early surgical aortic valve replacement.

In multivariable-adjusted analysis, they had significantly higher LVEF and lower right ventricular systolic pressure over time than patients managed with clinical surveillance, who worsened in both of those parameters over the study period.
  • #49 AVR for Moderate Aortic Stenosis

    Both TAVR and SAVR groups demonstrated significant benefit over clinical surveillance. […] Our study findings, especially in light of treatment advances and increased understanding of the poor prognosis associated with moderate AS, make us more inclined to offer intervention to our patients earlier in the disease process, Dr. Kapadia concludes. […] It has become clear in a number of studies, he continues, that patients undergoing AVR do not always enjoy the survival benefit expected. This paper provides further insights into this phenomenon and raises the question of whether AVR should be performed at an earlier stage, at least at centers with outstanding procedural outcomes for SAVR and TAVR. […] Given these important findings, intervening on moderate AS seems justified, and using safe, minimally invasive techniques to improve patient experience and outcomes may help avoid progression of heart failure due to AS.

    https://bjcardio.co.uk/2010/11/establishing-an-aortic-stenosis-surveillance-clinic/
    The number of patients with aortic stenosis (AS) in the UK is increasing. […] Establishment of a national AS surveillance programme could result in a large number of patients (9,000) being discharged from formal doctor-led cardiology clinic review in the UK. This would improve quality and consistency of follow-up monitoring for the patient and free up capacity to see new patients. […] Aortic stenosis (AS) is the most common form of valvular heart disease. The incidence is increasing due to an ageing population. […] Within the UK, demand for specialist cardiology services continues to increase. […] An AS surveillance clinic can result in a modest reduction in patients attending the cardiology out-patient department. […] Widespread national implementation of such clinics should be considered.

    However, several investigations have demonstrated that this is a simplistic approach. […] A multimodality cardiac imaging approach (MCI) plays a key role in these scenarios. […] The addition of complementary techniques such as transesophageal echocardiography (TEE), multidetector computed tomography (MDCT), and cardiac magnetic resonance (CMR) allows a proper grading in most cases. […] The objective of this review is to delve into the MCI used in the assessment of AS, highlighting the usefulness, strengths, and weaknesses of each imaging test, particularly in specific cases in which the grading of the disease is challenging. […] In many cases, severe aortic stenosis is not a straightforward diagnosis. […] In all these challenging scenarios, multimodality cardiac imaging can lead to a higher precision grading and a better decision-making process.

    FDA approved the Sapien 3 transcatheter aortic valve replacement (TAVR) platform for treatment of severe aortic stenosis early in the disease process while patients still had no symptoms or other indication for aortic valve replacement, marking the first approval for TAVR in asymptomatic patients, Edwards Lifesciences announced today. […] TAVR is well established for severe aortic stenosis patients with symptoms across surgical risk categories, but guidelines recommend routine monitoring every 6 to 12 months for asymptomatic patients. […] „There is an urgent need to change practice and TAVR guidelines for the treatment of aortic stenosis patients, which currently recommend 'watchful waiting’ until symptoms develop,” according to a statement from EARLY TAVR lead author Philippe Genereux, MD, director of the structural heart program at Gagnon Cardiovascular Institute in Morristown, New Jersey.

    https://jtd.amegroups.org/article/view/90835/html
    Therefore, it is paramount that awareness amongst physicians of the sex-related disparities in treating severe AS is raised to abolish the current healthcare gap between the sexes. […] Compared to men, women with severe AS are more symptomatic, older, frailer, have lower body mass index (BMI), exhibit higher operative risk, and often belong to New York Heart Association (NYHA) class III/IV. […] In women, SAVR may be technically more demanding and complicated due to sex-specific pathophysiological differences, such as smaller annular sizes and LVOT dimensions linked to concentric LVH. […] Despite significant advancements in TAVR procedures, disparities in outcomes, including mortality rates between male and female patients, exist. […] Therefore, careful consideration and appropriate antithrombotic therapies should be employed to prevent thrombotic complications.
