Double ventricular rupture after acute myocardial infarction: A rare case report

Abstract

A previously asymptomatic 53-year-old male presented 5 days after an acute anterior wall myocardial infarction, who was fibrinolytic naïve, with worsening dyspnea. Transthoracic echocardiographic evaluation revealed rupture of the interventricular septum and pseudoaneurysm of the left ventricle, confirmed by angiography. Coronary angiogram revealed multivessel disease. The patient underwent successful closure of ventricular septal rupture with repair of pseudoaneurysm and saphenous vein grafts to posterior descending branch of right coronary artery and obtuse marginal branch of left circumflex artery. Double ventricular ruptures following acute myocardial infarction are very rare with a reported incidence of 0.3% from various series in the revascularization era. They are also associated with exceedingly high mortality rates reaching up to 50%, even when intervened emergently.
