Thirty-five patients with clinical evidence of aortic insufficiency were studied by echocardiography. Eleven patients had characteristic diastolic fluttering of the mitral valve (30 to 40 Hz, maximal amplitude 4 mm). In five others the fluttering was classified as equivocal.

In a control group of 500 echocardiograms in patients without evidence of aortic insufficiency, there were three examples of equivocal fluttering. Atrial fibrillation also produces diastolic fluttering but of slower frequency.

Key Words: Echocardiogram • Ultrasound • Austin Flint murmur
