Mitral Stenosis Information - mitral valve stenosis

What is Mitral Stenosis

Nearly all patients with mitral stenosis have underlying rheumatic heart disease, though a history of rheumatic fever is often absent.

Clinical Findings of Mitral Stenosis

Symptoms and Signs of Mitral Stenosis

A characteristic finding of mitral stenosis is a localized middiastolic murmur low in pitch whose duration varies with the severity of the stenosis and the heart rate. Because it is thickened, the valve opens in early diastole with an opening snap. The sound is sharp, is widely distributed over the chest, and occurs early after A2 in severe and later in milder varieties of mitral stenosis. In severe mitral stenosis with low flow across the mitral valve, the murmur may be soft and difficult to find, but the opening snap can usually be heard. If the patient has both mitral stenosis and mitral regurgitation, the dominant features may be the systolic murmur of mitral regurgitation with or without a short diastolic murmur and a delayed opening snap.
