A 55-year-old man with a holosystolic murmur of increasing intensity has been seen regularly by his family physician for the past 3 years. He is referred to a cardiologist. The patient reports no shortness of breath, chest pain, or palpitations. An electrocardiogram shows normal sinus rhythm. A transthoracic echocardiogram reveals severe, anteriorly directed mitral regurgitation with isolated prolapse of the middle scallop of the posterior leaflet. Flow reversal is detected in the pulmonary veins. The calculated regurgitant volume is 75 ml, the regurgitant fraction 63%, and the effective regurgitant orifice 53 mm(2), features consistent with severe mitral regurgitation. The transthoracic echocardiogram also shows mildly depressed left ventricular function (ejection fraction, 58%), slightly elevated left ventricular dimensions (end-systolic dimension, 42 mm), and normal right ventricular systolic pressure. The patient is referred to a cardiac surgeon for consideration of mitral-valve repair.
