The echocardiographic diagnosis of calcified mitral annulus

Abstract

Echocardiograms were recorded in six patients with calcification of the mitral annulus. Echocardiographic sweep from the aorta to the left ventricular cavity revealed dense echoes, representing annulus calcification, posterior to the mitral valve. Characteristic calcium deposits in the region of the mitral annulus were detected on the chest roentgenogram of only a single subject. Cardiac fluoroscopy fluoroscopy demonstrated calcified mitral annulus in all patients. In one patient, coexisting calcified mitral annulus and proven pericardial effusion were diagnosed echocardiographically. It is concluded that the echocardiogram represents a useful noninvasive technic for the diagnosis of calcified mitral annulus.
