Giant extracardiac unruptured sinus of Valsalva aneurysm in a patient with left ventricular dysfunction

Abstract

Extracardiac unruptured sinus of Valsalva aneurysm (SVA) is an infrequent cardiac anomaly. Unruptured SVAs are typically symptom-free until rupture occurs. We describe a case of an unruptured extracardiac SVA originating from noncoronary sinus with left ventricular dysfunction. The patient was asymptomatic. The diagnosis was made by transthoracic echocardiography, computed tomography, and cardiac catheterization. The aneurysm was surgically resected and the sinus was successfully reconstructed with a patch. The patient remained asymptomatic throughout the postoperative follow-up period. Early surgical repair should be the choice of treatment for extracardiac SVAs in order to prevent sudden death.
