[An unusual case of postinfarction ventricular septal rupture in a patient with angiographically normal coronary arteries].

Ventricular septal defect is a rare but potentially fatal complication of acute myocardial infarction. It usually occurs during the first episode of myocardial infarction, most often in patients with single vessel coronary artery disease and total occlusion of the culprit vessel, in the absence of an adequate collateral circulation. However, this complication is observed in patients with myocardial infarction with normal coronary arteries and its pathogenesis may be attributed to different mechanisms such as inflammation, hypercoagulable state or coronary vasospasm. We report the case of a 59-year-old female patient with anteroseptal myocardial infarction developed 4 days after admission, complicated by ventricular septal defect with signs of congestive heart failure and angiographically normal coronary arteries.
