Final answer:
Findings in rheumatic mitral valve stenosis include decreased E-F slope, thickened mitral valve leaflets, and B notch, but not anterior motion of the posterior mitral valve leaflet, which is not typically seen in this disease.
Step-by-step explanation:
Mitral valve stenosis, often a result of rheumatic heart disease, can be evaluated using M-mode echocardiography, which provides valuable information about the motion and structure of the mitral valve leaflets.
The mitral valve findings in patients with rheumatic mitral valve stenosis typically include a decreased E-F slope of the anterior mitral leaflet, signifying reduced leaflet mobility during diastole. Patients also exhibit thickened mitral valve leaflets due to fibrotic changes and calcification. However, one characteristic that is not commonly associated with mitral valve stenosis is anterior motion of the posterior mitral valve leaflet. Instead, the posterior leaflet motion is often restricted due to adhesions and thickening of the valve.
Findings such as the B notch on the anterior mitral valve leaflet are indicative of increased stiffness and delayed relaxation of the valve, which also corresponds to the pathophysiology of rheumatic mitral stenosis.
