Abstract

Sinus of Valsalva aneurysms are a rare entity. Rupture of such aneurysms is a major cause of aortocardiac fistulas usually occurring between the right sinus of Valsalva and right cardiac chambers. We report an exceptional case of a ruptured congenital sinus of Valsalva aneurysm with fistulas involving both the right- and left-ventricular outflow tracts and causing RVOT obstruction. We also demonstrate the utility of computed tomography angiography and transesophageal echocardiography in diagnosing these fistulas.
