[Rupture of interventricular septum and ventricular aneurysm secondary to acute myocardial infarction in a case with normal coronary arteries (author's transl)].

A patient with ventricular septal defect and ventricular aneurysm after an acute myocardial infarction with normal coronary arteries is reported. Heart failure at 3 weeks after acute myocardial infarction was the indication for surgical treatment. The patient was successfully operated upon with resection of the aneurysm and closure of the ventricular septal defect. Coronary angiography performed before and after cardiac surgery demonstrated a normal coronary tree with transient systolic subocclusion of the left anterior descending coronary artery. The implication of a muscular bridge on the complications of myocardial infarction are discussed.
