Congenital absence of the left pericardium: an unusual palpation finding and echocardiographic demonstration of the defect.
A patient with classical clinical and roentgenographic features of congenital absence of the left pericardium is described. On physical examination in the supine position, the precordial apical impluse was markedly displaced laterally. In the left lateral decubitus position, however, the apical impulse was felt in a mor medial location. This apparently paradoxical movement of the apical impulse was not found in persons with normal hearts or with left ventricular enlargement of hypertrophy, and may be characteristic of the pericardial defect. Further, with echocardiography we were able to demonstrate the absence of a pericardial echo on the lateral surface of the heart. Thus, echocardiography may be a useful noninvasive tool in the diagnosis of this defect.
