The syndrome of systolic click and late systolic murmur is due to ballooning or prolapse into the left atrium of one or both mitral valve leaflets during ventricular systole and with resulting mitral regurgitation and the characteristic murmur. The click results from sudden tensing of the chordae tendinae. This report deals with the echocardiographic findings in four patients with this syndrome, as well as two without this syndrome, but with similar echocardiographic findings. Two of the four patients with the syndrome revealed mid- systolic posterior movement of the anterior leaflet of the mitral valve. The posterior mitral valve leaflet could not be recorded. In the other two patients, an interface just posterior to the anterior leaflet echo showed separation and posterior movement of both components of the interface during late systole, suggesting posterior prolapse of both leaflets of the valve. Thus all four showed anterior leaflet prolapse, and two probable posterior leaflet prolapse as well. In all, diastolic movements were normal. Two patients, one with bifascicular block, aortic regurgitation, and the late murmur of mitral regurgitation, and another with ischemic and hypertensive heart disease and a late mitral murmur were studied. The curve of anterior motion of valve structures during systole was interrupted by posterior displacement in late systole suggesting systolic prolapse of the mitral valve in both cases. The E-F slope was not abnormally rapid in either. These studies suggest that ultrasoundcardiography is useful in differentiating mitral regurgitation due to abnormal supporting structures which is usually hemodynamically benign from more significant mitral regurgitation, by observing systolic prolapse in the former, and its absence with or without abnormal diastolic movements in the latter.
