title: Intraoperative two-dimensional echocardiography in complicated infective endocarditis of the aortic valve.
abstract: Six patients with complicated native and prosthetic aortic valve endocarditis were operated on. The data from cineangiocardiography and from precordial and intraoperative two-dimensional echocardiography were compared with the surgical findings. Surgical inspection revealed a mycotic aneurysm in six patients. In addition, a fistulous connection to the right atrium, an abscess in the interventricular septum, and mitral valve endocarditis were found in one of the patients. The pathologic conditions disclosed during the operation were correctly visualized with two-dimensional epicardial echocardiography, done before cardiopulmonary bypass. Cineangiography provided this information in one patient, and precordial two-dimensional echocardiographic analysis was correct in two patients. Thus, intraoperative two-dimensional echocardiography provides detailed information in complicated native and prosthetic aortic valve endocarditis that is of importance in the surgical management.
