Zwężenie mitralne
Diagnostyka i diagnoza

Zwężenie zastawki mitralnej charakteryzuje się ograniczeniem przepływu krwi z lewego przedsionka do lewej komory, co prowadzi do objawów zastoju płucnego i powikłań hemodynamicznych. Diagnostyka opiera się na badaniu fizykalnym (szmer rozkurczowy, trzask otwarcia zastawki, głośny ton S1) oraz przede wszystkim na echokardiografii, która jest złotym standardem. Echokardiografia przezklatkowa (TTE) i przezprzełykowa (TEE) umożliwiają ocenę morfologii zastawki, pola powierzchni (prawidłowo 4-5 cm²), gradientu ciśnień i czasu półtrwania gradientu (pressure half-time). Zwężenie umiarkowane definiuje się jako pole powierzchni 1,5-2,5 cm² lub czas półtrwania ≥150 ms, a ciężkie jako pole ≤1,5 cm² lub czas półtrwania >150 ms. Dodatkowo stosuje się badania obrazowe (RTG, CT, CMR) oraz EKG i monitorowanie Holterowskie w celu oceny powikłań, takich jak powiększenie lewego przedsionka czy migotanie przedsionków.

Diagnostyka zwężenia mitralnego

Zwężenie mitralne (zwężenie zastawki mitralnej) to stan, w którym dochodzi do zwężenia ujścia zastawki dwudzielnej, co prowadzi do ograniczenia przepływu krwi z lewego przedsionka do lewej komory serca. Diagnostyka tego schorzenia jest procesem wieloetapowym, wymagającym zastosowania różnych metod diagnostycznych w celu potwierdzenia rozpoznania i oceny stopnia zaawansowania choroby.123

Badanie fizykalne i wywiad

Pierwszym krokiem w diagnostyce zwężenia mitralnego jest dokładne badanie fizykalne i szczegółowy wywiad medyczny. Lekarz zbiera informacje dotyczące objawów, historii medycznej pacjenta oraz potencjalnych czynników ryzyka, takich jak przebyta gorączka reumatyczna.45

Podczas badania fizykalnego lekarz osłuchuje serce za pomocą stetoskopu, poszukując charakterystycznych oznak zwężenia mitralnego:67

  • Szmer serca (najczęściej szmer rozkurczowy o niskiej częstotliwości, przypominający dudnienie)
  • Trzask otwarcia zastawki mitralnej
  • Głośny pierwszy ton serca (S1)
  • Objawy zastoju w płucach

89

Szmer serca jest jednym z najwcześniejszych i najłatwiejszych do wykrycia objawów zwężenia mitralnego. Lekarz może zazwyczaj usłyszeć ten szmer podczas rutynowego badania fizykalnego. W przypadkach bardziej zaawansowanych szmer może składać się z więcej niż jednego dźwięku, co może pomóc lekarzowi w określeniu stopnia nasilenia choroby.1011

Badania obrazowe

Echokardiografia

Echokardiografia jest złotym standardem w diagnostyce zwężenia mitralnego. Jest to nieinwazyjne badanie wykorzystujące fale ultradźwiękowe do uzyskania obrazu serca w ruchu. Pozwala na dokładną ocenę struktury zastawki mitralnej, jej funkcji oraz przepływu krwi.1213

Wyróżniamy dwa podstawowe rodzaje echokardiografii:1415

  • Echokardiografia przezklatkowa (TTE) – standardowe badanie wykonywane przez klatkę piersiową, które pozwala ocenić kształt i funkcję serca oraz zastawki mitralnej
  • Echokardiografia przezprzełykowa (TEE) – bardziej szczegółowe badanie, w którym sonda ultradźwiękowa jest wprowadzana do przełyku, co umożliwia dokładniejsze obrazowanie zastawki mitralnej

1617

Echokardiografia z wykorzystaniem techniki Dopplera pozwala na dokładną ocenę stopnia zwężenia zastawki mitralnej poprzez pomiar:1819

  • Pola powierzchni zastawki mitralnej (prawidłowo 4-5 cm²)
  • Gradientu ciśnień przez zastawkę
  • Czasu półtrwania gradientu ciśnienia (pressure half-time)
  • Ciśnienia w tętnicy płucnej

2021

Na podstawie badania echokardiograficznego można sklasyfikować stopień zwężenia mitralnego:22

  • Umiarkowane zwężenie: pole powierzchni zastawki 1,5-2,5 cm² lub czas półtrwania gradientu ciśnienia ≥150 ms
  • Ciężkie zwężenie: pole powierzchni zastawki ≤1,5 cm² lub czas półtrwania gradientu ciśnienia >150 ms

2324

Inne badania obrazowe

Oprócz echokardiografii, w diagnostyce zwężenia mitralnego stosuje się również inne badania obrazowe:2526

  • Zdjęcie rentgenowskie klatki piersiowej – może wykazać powiększenie lewego przedsionka, zastój w płucach oraz poszerzenie rozwidlenia tchawicy
  • Tomografia komputerowa (CT) – pozwala na uzyskanie trójwymiarowego obrazu serca i dokładną ocenę stopnia zwapnienia zastawki
  • Rezonans magnetyczny serca (CMR) – dostarcza szczegółowych obrazów struktur serca i jest szczególnie przydatny w ocenie stopnia ciężkości zwężenia mitralnego

2728

Badania elektrofizjologiczne

W diagnostyce zwężenia mitralnego stosuje się również badania oceniające elektryczną aktywność serca:2930

  • Elektrokardiogram (EKG) – może wykazać powiększenie lewego przedsionka (objawia się falą P trwającą >0,12 s z wyraźnym ujemnym wychyleniem końcowego komponentu w odprowadzeniu V1 lub szerokimi, wcięciem falami P w odprowadzeniu II) oraz przerost prawej komory
  • Monitorowanie holterowskie – 24-godzinne badanie EKG pozwalające na wykrycie zaburzeń rytmu serca, szczególnie migotania przedsionków, które często towarzyszy zwężeniu mitralnemu

3132

Testy wysiłkowe

Testy wysiłkowe są ważnym elementem diagnostyki zwężenia mitralnego, szczególnie u pacjentów, którzy zgłaszają objawy tylko podczas wysiłku lub u których występuje rozbieżność między objawami a wynikami badań w spoczynku.3334

Echokardiografia wysiłkowa pozwala na ocenę zmian gradientu zastawki oraz ciśnienia płucnego w odpowiedzi na wysiłek fizyczny. Jest to przydatne narzędzie do oceny funkcjonalnego znaczenia zwężenia mitralnego i może pomóc w wyborze optymalnego momentu interwencji.3536

Cewnikowanie serca

Cewnikowanie serca jest inwazyjną metodą diagnostyczną, która pozwala na bezpośredni pomiar ciśnienia w jamach serca oraz ocenę gradientu przez zastawkę mitralną. Obecnie nie jest rutynowo stosowane w diagnostyce zwężenia mitralnego, ale może być wykonane w następujących sytuacjach:3738

  • Gdy wyniki badań nieinwazyjnych są niejednoznaczne
  • Gdy istnieje rozbieżność między objawami klinicznymi a wynikami badań nieinwazyjnych
  • W ramach przedoperacyjnej oceny choroby wieńcowej u pacjentów planowanych do leczenia operacyjnego

3940

Podczas cewnikowania serca można ocenić:4142

  • Gradient ciśnień przez zastawkę mitralną
  • Ciśnienie w lewym przedsionku i tętnicy płucnej
  • Pole powierzchni zastawki mitralnej (obliczone za pomocą równania Gorlina)
  • Stan tętnic wieńcowych (koronarografia)

4344

Klasyfikacja stopni zwężenia mitralnego

Według wytycznych American College of Cardiology/American Heart Association (ACC/AHA) z 2020 roku, zwężenie mitralne klasyfikuje się na cztery stopnie (A-D) na podstawie anatomii zastawki, parametrów hemodynamicznych, następstw hemodynamicznych zwężenia oraz obecności lub braku objawów:4546

Stopień Charakterystyka Anatomia zastawki Parametry hemodynamiczne Objawy
A (ryzyko zwężenia mitralnego) Łagodne uwypuklenie płatków w rozkurczu Prawidłowa hemodynamika zastawki Prawidłowe Brak
B (postępujące zwężenie mitralne) Zmiany reumatyczne zastawki, w tym zrośnięcie komisur i uwypuklenie płatków w rozkurczu Łagodne do umiarkowanych zaburzeń hemodynamicznych Pole powierzchni >1,5 cm², czas półtrwania gradientu <150 ms Brak
C (bezobjawowe ciężkie zwężenie mitralne) Zmiany reumatyczne zastawki jak w stopniu B Ciężkie zaburzenia hemodynamiczne Pole powierzchni ≤1,5 cm², czas półtrwania gradientu ≥150 ms Brak
D (objawowe ciężkie zwężenie mitralne) Zmiany reumatyczne zastawki jak w stopniu C Ciężkie zaburzenia hemodynamiczne Pole powierzchni ≤1,5 cm², czas półtrwania gradientu ≥150 ms Obecne (zmniejszona tolerancja wysiłku, duszność wysiłkowa)

4748

Monitorowanie pacjentów z zwężeniem mitralnym

Pacjenci z rozpoznanym zwężeniem mitralnym wymagają regularnego monitorowania, nawet jeśli nie występują u nich objawy. Częstotliwość kontroli zależy od stopnia zwężenia:4950

  • Pacjenci z bardzo ciężkim zwężeniem mitralnym powinni mieć wykonywane badanie echokardiograficzne raz w roku
  • Pacjenci z łagodniejszymi formami zwężenia mitralnego wymagają badania echokardiograficznego co 3-5 lat

5152

Diagnostyka różnicowa

W procesie diagnostycznym zwężenia mitralnego należy uwzględnić inne schorzenia, które mogą dawać podobne objawy lub współistnieć z tą chorobą:5354

  • Niedomykalność zastawki mitralnej
  • Zwężenie zastawki aortalnej
  • Niedomykalność zastawki trójdzielnej
  • Infekcyjne zapalenie wsierdzia
  • Wady wrodzone serca (np. ubytek przegrody międzykomorowej)
  • Kardiomiopatia przerostowa
  • Zaciskające zapalenie osierdzia

5556

Wnioski i zalecenia dotyczące diagnostyki

Diagnostyka zwężenia mitralnego powinna być prowadzona w sposób kompleksowy, z wykorzystaniem różnych metod diagnostycznych. Kluczowe zalecenia obejmują:5758

  1. Echokardiografia przezklatkowa jest badaniem pierwszego wyboru w diagnostyce zwężenia mitralnego i powinna być wykonana u wszystkich pacjentów z podejrzeniem tej choroby
  2. Echokardiografia przezprzełykowa jest wskazana, gdy obrazowanie przezklatkowe jest nieoptymalne lub gdy konieczna jest dokładniejsza ocena zastawki mitralnej
  3. Testy wysiłkowe są przydatne u pacjentów z rozbieżnością między objawami a wynikami badań w spoczynku
  4. Cewnikowanie serca powinno być wykonane, gdy wyniki badań nieinwazyjnych są niejednoznaczne lub istnieje rozbieżność między objawami klinicznymi a wynikami badań nieinwazyjnych
  5. Regularny monitoring jest konieczny u wszystkich pacjentów z rozpoznanym zwężeniem mitralnym, nawet jeśli nie występują u nich objawy

5960

W większości przypadków diagnostyka zwężenia mitralnego może być przeprowadzona przy użyciu metod nieinwazyjnych, z echokardiografią jako podstawowym narzędziem diagnostycznym. Wczesne rozpoznanie i odpowiednie monitorowanie pozwalają na optymalne leczenie i zapobieganie powikłaniom, takim jak niewydolność serca, nadciśnienie płucne czy zaburzenia rytmu serca.6162

    To determine if a patient has mitral valve stenosis, the physician will ask questions about family history and symptoms and listen to the patients heart with a stethoscope. The physician will also listen for a buildup of fluid in the lungs. We use advanced diagnostic procedures and technology to effectively diagnose, inform treatment and carefully monitor the condition. Diagnostic procedures can include: […] Cardiac catheterization: During this test, a long, thin flexible tube is threaded through a blood vessel in the arm or groin and to the heart. Contrast material is injected through the tube and a type of X-ray movie is taken to show how the aortic valve functions. […] Chest X-ray: X-rays are common imaging tests of the heart and aorta. […] Echocardiogram: This ultrasound exam uses soundwaves to take moving pictures of the hearts chambers and valves.
  • #17 Mitral Valve Stenosis Diagnosis | Temple Health
    https://www.templehealth.org/services/conditions/mitral-valve-stenosis/diagnosis
    Heart catheterization is used to detect abnormalities of the heart valves, heart function and coronary arteries. This procedure uses a catheter (long thin flexible tube) that is inserted through a blood vessel in the wrist, leg, arm or neck to measure the pressure of blood in the heart chambers, take blood samples or view heart structures (using contrast dye). […] Transesophageal Echocardiogram (TEE) uses sound waves (ultrasound) to create detailed pictures of your heart and arteries. Unlike echocardiogram, TEE uses a probe that is passed through the mouth and into the esophagus. This provides a better picture because the esophagus is right behind the heart and the probe does not have to penetrate the chest wall in the ribs and lungs to get a clear picture. […] Electrocardiogram (ECG or EKG) is a simple non-invasive test that can be done in the doctors office using small adhesive pads called electrodes that are placed on the arms, legs, and chest. These electrodes are connected to a machine that detects and prints out the heart’s electrical impulses, giving a 10-second snapshot of what the heart is doing right at that moment.

    https://www.merckmanuals.com/professional/cardiovascular-disorders/valvular-disorders/mitral-stenosis
    Diagnosis of mitral stenosis is suspected clinically and confirmed by echocardiography. Typically, 2-dimensional echocardiography shows abnormal valve and subvalvular structures. It also provides information about the degree of valvular calcification and stenosis and LA size. Doppler echocardiography provides information about the transvalvular gradient and pulmonary artery pressure. The normal area of the mitral valve orifice is 4 to 5 cm2. […] Severity of mitral stenosis is characterized echocardiographically as moderate: Valve area 1.5 to 2.5 cm2 or diastolic pressure half-time 150 msec; severe: Valve area 1.5 cm2 or diastolic pressure half-time 150 msec; symptoms are often present. […] However, the relationship between the area of the valve orifice and symptoms is not always consistent. Color Doppler echocardiography detects associated mitral regurgitation. Transesophageal echocardiography (TEE) can be used to detect or exclude small LA thrombi, especially those in the LA appendage, which usually cannot be seen transthoracically. TEE also can better assess mitral regurgitation when mitral calcification causes acoustic shadowing of the left atrium from the transthoracic window.
  • #20 Mitral Stenosis – The Cardiology Advisor
    https://www.thecardiologyadvisor.com/ddi/mitral-valve-stenosis/
    The diagnostic workup of mitral stenosis includes noninvasive approaches (for example, auscultation, electrocardiogram [ECG], chest imaging, echocardiogram and exercise echocardiogram) and invasive approaches (for example, cardiac catheterization).1 […] Because enlargement of the left atrium may be present in patients with MS, ECG findings may be consistent with left atrial enlargement.4 An increased P-wave area of greater than 24 ms x mv measured from ECG lead II typically indicates that atrial enlargement associated with mitral stenosis is present.4 […] However, the primary mode of evaluation for MS is echocardiography, because it allows for a detailed assessment of cardiac anatomy and hemodynamics in patients with mitral stenosis.3 Mitral stenosis grading is based on echocardiographic criteria and includes the Wilkins score, which assesses leaflet mobility, thickness, calcification, and subvalvular thickening, and the Padial score, which specifically grades mitral valve leaflet thickening.1
  • #21 Mitral valve stenosis – Echocardiography, diagnosis, causes, severity
    https://ecgwaves.com/topic/mitral-valve-stenosis/
    Mitral stenosis is defined as a narrowing of the mitral valve orifice. […] Most causes of mitral stenosis yield a progressive narrowing of the mitral valve. […] Mitral stenosis typically becomes symptomatic at rest when the valve area is reduced to 1.5 cm2. During physical activity, mitral stenosis may become symptomatic already at 2.5 cm2. […] Echocardiographic assessment of mitral stenosis includes visual and 2D imaging, as well as Doppler measurements to assess the degree of stenosis and evaluation of complications. […] The severity of mitral stenosis is classified on the basis of valve area and pressure gradients across the valve. […] Valve area is a key parameter in the assessment of disease severity. […] The mean pressure gradient (difference) and maximum pressure gradient are calculated using continuous wave Doppler through the mitral valve (apical view).

    Diagnosis of mitral stenosis is suspected clinically and confirmed by echocardiography. Typically, 2-dimensional echocardiography shows abnormal valve and subvalvular structures. It also provides information about the degree of valvular calcification and stenosis and LA size. Doppler echocardiography provides information about the transvalvular gradient and pulmonary artery pressure. The normal area of the mitral valve orifice is 4 to 5 cm2. […] Severity of mitral stenosis is characterized echocardiographically as moderate: Valve area 1.5 to 2.5 cm2 or diastolic pressure half-time 150 msec; severe: Valve area 1.5 cm2 or diastolic pressure half-time 150 msec; symptoms are often present. […] However, the relationship between the area of the valve orifice and symptoms is not always consistent. Color Doppler echocardiography detects associated mitral regurgitation. Transesophageal echocardiography (TEE) can be used to detect or exclude small LA thrombi, especially those in the LA appendage, which usually cannot be seen transthoracically. TEE also can better assess mitral regurgitation when mitral calcification causes acoustic shadowing of the left atrium from the transthoracic window.

    Transthoracic echocardiography (TEE) is the primary approach to both diagnosis and pathophysiologic evaluation of mitral stenosis. […] The two most important measurements made on echocardiography are the pressure half-time and the mitral valve area. […] The 2020 ACC/AHA Guidelines categorize MS into four distinct stages (Stage A through D) on the basis of valve anatomy, valve hemodynamics, hemodynamic consequences of valve obstruction and the presence or absence of symptoms. […] Stage A disease (at risk of MS) is characterized by mild valve doming in diastole with otherwise normal valve hemodynamics and an absence of symptoms. […] Stage B (progressive) mitral stenosis is typified by rheumatic changes in the mitral valve, including fusion of the commissures, as well as valve doming in diastole.

    The above-mentioned differences between the 2 types of MS create diagnostic challenges as the echocardiographic tools that have been validated in prior studies to be used to diagnose the severity of RMS cannot be applied for the accurate diagnosis of DMS. […] This review tackles some of the current diagnostic challenges to accurately assess the severity of DMS in the light of echocardiographic predictors of poor prognosis. […] The continuity equation is an extrapolation of the concept of conservation of mass, and states that in the absence of valvular regurgitation or intracardiac shunting, the trans-mitral stroke volume (SV) should be equal to the SV determined at the level of the left ventricular outflow tract (LVOT) or right ventricular outflow tract (RVOT). […] A DMSI of 0.35 to 0.50 is consistent with severe DMS (MVA ≤1.5 cm²), and a DMSI <0.35 suggests very severe calcific MS (MVA ≤1.0 cm²).

[…] The MR murmur should be differentiated from the systolic murmurs of aortic stenosis (AS), TR and ventricular septal defect (VSD). […] Dynamic auscultation helps to differentiate MR from other systolic murmurs. […] A careful auscultation can go a long way to diagnose and assess the severity of mitral valve disease and to differentiate it from similar cardiac conditions. […] However, auscultatory findings should only be used in combination with symptoms and other physical findings and results of imaging and other investigation results to diagnose and treat mitral valve disease.

    In the presence of 2D echocardiographic features of MS, Color Doppler can confirm the diagnosis of MS. […] The assessment of the severity of MS is based on the estimation of valve area. […] The severity can be assessed as mild (5), moderate (5-10), and severe (10). […] The detection and quantitation of associated mitral regurgitation have important implications for the choice of intervention. […] The presence of MR does not alter the validity of the quantitation of MS. […] Accurate diagnosis and appropriate hemodynamic assessment are significantly important since they have therapeutic implications. […] Patients with critical valvular disease usually fail to respond to medical therapy alone. […] The goal of medical therapy and mechanical circulatory support (MCS) is stabilization prior to definitive correction of the lesion.

    The effect of positive pressure ventilation (PPV) among patients with valvular emergencies is variable. […] When MCS is indicated, early application is preferred to reduce the need for vasopressors and inotropes. […] Cardiac surgeon consultation is warranted early for valvular emergencies. […] The main problem in MS is inadequate LV preload. […] Having said that, the main problem in MS is inadequate LV preload. […] In hemodynamically stable patients, medical therapy may be helpful for symptomatic relief. […] Since MS is a mechanical disorder, once valve obstruction is present, only intervention provides sustained symptom control and improved survival. […] Decisions on whether and how to intervene are largely based on the following criteria: The stage of MS. […] The stages of MS are defined by patient symptoms, valve anatomy, valve hemodynamics, and the consequences of valve obstruction on the left atrium (LA) and pulmonary circulation. […] Indications for intervention in patients with rheumatic MS include severe MS (MVA 1.5 cm2) who are either symptomatic or asymptomatic with elevated pulmonary artery systolic pressure (PASP; 50 mmHg) or AF.

    This review provides an update on rheumatic mitral stenosis. Acute rheumatic fever (RF), the sequela of group A -hemolytic streptococcal infection, is the major etiology for mitral stenosis (MS). […] Pre-procedural evaluation for treatment of MS using a multimodality approach with 2D and 3D transthoracic and transesophageal echo, stress echo, cardiac CT scanning, and cardiac MRI as well as hemodynamic assessment by cardiac catheterization is discussed. […] It is also important to understand the indications as well as morphological MV characteristics to identify the appropriate treatment with PMBC or surgery.

    All patients with suspected mitral stenosis should undergo transthoracic echocardiography (TTE). TTE is the best initial test to evaluate the mitral valve and quantify the anatomical extent of the stenosis. […] TTE is the most important test for diagnosing and guiding the treatment of mitral stenosis. […] Characteristic findings include: Reduced mitral valve area (MVA): 1.5 cm2 is considered to be severe MS. […] MVA, valve pressure gradient, and presence or absence of symptoms and pulmonary artery hypertension are used to grade the severity of disease. […] Further studies are indicated in select patients when TTE findings are unclear or do not correlate with symptoms, or when an intervention is planned. […] Transesophageal echocardiography (TEE) is indicated to confirm the diagnosis if TTE examination is technically suboptimal. […] Stress testing is useful when symptoms do not correlate with echocardiographic findings. […] Cardiac catheterization is indicated if other conditions make staging unclear.

    In patients with RMS, Doppler-derived mean TMG values correlate well with invasive measurements obtained via trans-septal catheterization. […] Diagnosing significant DMS is crucial as worst outcomes have been reported in patient with severe mitral stenosis undergoing TAVR (higher in-hospital mortality and heart failure-related hospitalization at 1-year in severe MS compared to those without MS). […] In symptomatic patients (NYHA class III or IV) with severe MS (i.e., mitral valve area ≤1.5 cm², Stage D) attributed to extensive MAC, valve intervention may be considered. […] If exercise cannot be performed, Dobutamine Stress Echocardiography (DSE) may be useful. […] In the absence of reliability of MV gradients and PHT that have been traditionally used for RMS, we are limited to the use of the continuity equation and its derivative (i.e., DMSI) along with 3-D MVA for stenosis severity assessment.

    Healthcare providers may talk about mitral valve stenosis stages. These range from A to D, with D being the most severe. At each stage, a provider may see irregularities in how your mitral valve looks or functions. Stages C and D have the most severe issues. You dont have symptoms until stage D. […] Mitral valve stenosis treatments can manage but not cure your condition. Once you have symptoms, its important to get mitral valve stenosis treatment sooner rather than later. By the time symptoms begin, the problem is often past the mild stage. […] Several different types of medicine (like beta-blockers, diuretics or blood thinners) can treat symptoms of mitral valve stenosis. […] Your healthcare provider can help guide you through what you can do to manage mitral valve stenosis. They may recommend: Follow-up monitoring and testing every six months to three years (depending on severity). […] If you develop the symptoms of mitral valve stenosis, especially ones that disrupt your life, you should contact your healthcare provider.

    Mitral stenosis is a progressive disease consisting of a slow, stable course in the early years followed by an accelerated course later in life. […] In the asymptomatic or minimally symptomatic patient, survival is greater than 80% at 10 years. […] When limiting symptoms occur, 10-year survival is less than 15% in the patient with untreated mitral stenosis. […] When severe pulmonary hypertension develops, mean survival is less than 3 years. […] Complications of mitral stenosis include the following: Atrial fibrillation, Systemic embolism due to left atrial thrombus formation mostly secondary to atrial fibrillation: 20% of patients with mitral stenosis and systemic embolism are in sinus rhythm. […] All patients should be informed about the following: Signs and symptoms of severe mitral stenosis (Patients should be advised to present for reevaluation.)
