Diastolic Mitral Regurgitation in Intact Mitral Valve Detected by Color Doppler Echocardiography in a Patient with Acute Aortic Regurgitation.

摘要

A 38-year-old man was admitted with coingestive heart failure due to infective endocarditis. Echocardiography with color Doppler imaging revealed severe aortic regurgitation, mitral valve premature closure and diastolic mitral regurgitation. The flow of the diastolic mitral regurgitation was directed to the posterior wall of the left atrium through just behind the posterior mitral leaflet. The diastolic mitral regurgitation was observed only in the period of late diastole and no mitral regurgitation could be detected in the systolic phase. After successful aortic valve replacement, the diastolic mitral regurgitation disappeared completely.
