[Echocardiography in the diagnosis of tetralogy of Fallot].

Echocardiography was performed in the examination of 35 patients with tetralogy of Fallot and 3 patients with pentalogy of Fallot. The echocardiogram demonstrated dextrodivision of the aortic root, interruption in the continuity of the interventricular septum and the anterior wall of the aorta, incomplete image of the interventricular septum in its upper part, distention of the aortic root, stenosis of the right ventricular infundibulum, and hypertrophy of the right ventricular myocardium. The presence and severity of all developmental anomalies of the heart and major vessels known as tatraology of Fallot may be identified by the echocardiography method in most cases.
