Abstract

We report two cases of postinfarction dissecting hematoma of the interventricular septum with restrictive ventricular septal defect that evolved as an inferobasal pseudoaneurysm. The difficult anatomical pattern was assessed by two-dimensional (2-D) echocardiography with Doppler and color analysis, left ventriculography and perioperative transoesophageal echo. Because the patient had no signs of heart failure, the surgical repair was successfully delayed until the dissecting tissue became fibrotic. Problems of diagnosis, decision making and surgical management are discussed.
