MDCT Findings of Sinus of Valsalva Aneurysms Involving Two Coronary Sinuses: Case Report

cardiac anomaly (1). SVA most commonly originates in the right coronary sinus of Valsalva (75-90%), the noncoronary sinus (10-25%), and rarely, in the left sinus (1, 2). Unruptured SVA usually remains asymptomatic, but it can sometimes cause cardiac arrhythmia, myocardial ischemia, or systemic embolic events (1-3). Multidetector computed tomography (MDCT) is a useful modality for examining the anatomy of the heart, but there have been few radiologic reports of sinus of Valsalva aneurysms diagnosed by MDCT. We report here a case of an unruptured leftand non-coronary sinus of Valsalva aneurysms detected by MDCT.
