title: Echocardiographic and clinical spectrum of mitral anular calcification.
abstract: To establish the reliability of echocardiography in making the diagnosis of mitral anular calcification 10 consecutive patients with dense echoes at the mitral anular area were examined fluoroscopically, using an image intensifier. Nine of these had distinct mitral anular calcification. The echocardiographic reliability thus confirmed, 30 cases with similar findings were reviewed and the total group of 40 cases were used to define the echocardiographic spectrum of mitral anular calcification. This lesion extended variably from the anulus to involve the posterior left ventricular wall, mitral valve leaflets, aortic root, aortic valve and interventricular septum. The pleomorphic echocardiographic findings introduce difficulties in the diagnosis of pericardial effusion and mitral stenosis. Echocardiography is a reliable method of diagnosing mitral anular calcification, but care must be taken to avoid confusing this condition with others it resembles.
