M-mode echocardiographic assessment of the valve reveals slow early diastolic closure of the mitral valve.The mid-diastolic closure velocity or E-F slope is remarkably reduced or sometimes even flat. The severity of MS can be assessed by cardiac catheterization. Mitral valve stenosis commonly leads to shortness of breath, especially during exercise or when lying down. The two most important factors to determine severity of MS are mitral valve area (MVA) and mean MV gradient (MG). 2. In those with pulmonary hypertension signs of this and right sided heart failure may also feature. The severity of stenosis is assessed using Doppler studies. M-mode Echocardiography. 11.4 Echocardiographic Findings in Mitral Stenosis Patients with atrial fibrillation and mitral stenosis should be anticoagulated with warfarin. MLS index less than 0.73 cm can predict severe MS with 93.2%. The clinical significance of a small amount of aortic regurgitation with an otherwise normal echocardiographic study is unknown. Doppler in mitral stenosis and regurgitation Grade 3: Thickening extending to the distal third of the chords. 52% of patients with 'definitely severe' MR by ASE algorithm had severe MR by CMR regurgitant volume vs. 38% with moderate and 10% with mild MR. "/> Two major factors determine the severity of mitral stenosis:the size of the mitral orifice during diastole (mitral valve area) and the magnitude of the gradients across the valve. Other common symptoms include: a cough, with or without blood. The degree of mitral stenosis is determined by the mean gradient of the mitral valve area Mild mitral stenosis <5 mmHg >1.5 cm2 Moderate mitral stenosis 5 - 10 mmHg 1.0 - 1.5 cm2 Severe mitral stenosis > 10 mmHg < 1.0 cm2 Mitral Regurgitation The mitral valve damage can either be congenital or because of factors such as calcification. Mitral Stenosis | SpringerLink However, the complex three-dimensional (3D) structure of the mitral valve (MV) poses challenges to accurate measurements of its orifice area by 2D imaging modalities. The analysis of the morphology of the mitral valve apparatus includes leaflet mobility and flexibility, leaflet thickness, leaflet calcification, subvalvular fusion, and the appearance of commissures. Mitral stenosis (MS) or mitral valve stenosis is the restrictive opening of the mitral valve (MV) resulting in an increase in the gradient pressure across the valve.

Commissural fusion and calcification if present can be seen well on PSAX view. Mitral stenosis presents 20 to 40 years after an episode of rheumatic fever. The guideline recommends engaging in shared decision-making based on a CHA2DS2-VASC score, which is a tool used to predict the. There are three methods to calculate valve area. Trans mitral gradient is better assessed in apical four chamber view by Doppler. Mitral stenosis (MS) causes obstruction to blood flow from the left atrium to left ventricle. There was a very strong correlation between MLS index and MVA by planimetry ( r = 0.89, p<0.001) and MVA by PHT (r=0.95, p<0.001). The Assessment of Mitral Stenosis by Phonocardiography Another update involves the use of valve replacement in patients with mitral regurgitation (MR). It is demonstrated that patients with MS had lower LV functions using 2D strain imaging, and this is independent of the hemodynamic severity of MS.

Rheumatic fever is the leading cause of mitral stenosis. According to The ESC 2012, the severity of MS is defined by a MVA< 1 cm2 and a MTG>10 mmHg, as long as this gradient is interpreted according to heart rate and in patients in sinus rhythm [12]. 2d two-dimensional, eroa effective Smith MD, Handshoe R, Handshoe S, Kwan OL, DeMaria AN. Accurate assessment of aberrations in diastolic function is important as these subjects often present with signs and symptoms of heart failure and pulmonary congestion that cannot be solely explained by the severity of mechanical obstruction. The average transmitter pressure gradient and the area of the mitral valve can be determined quite accurately using continuous-wave technology. Circulation. Trace mitral, tricuspid and pulmonic regurgitation can be detected in 70% to 90% of normal individuals and has no adverse clinical implications. The CXR shown below has a number of signs indicative of left atrial enlargement: Severe MS is defined by a mitral valve area (MVA) 1.5 cm 2, but even with this degree of narrowing, mean mitral gradients (MGs) can vary considerably given their dependence on flow (stroke volume [SV]) and heart rate. fatigue . This document gives recommendations for the image and analysis dataset required in patients being assessed for mitral Stenosis, since echocardiography plays a major role in diagnosis, quantitation of disease severity and analysis of valve anatomy.
