Anomalous origin of the left coronary artery (LCA) from the right sinus of Valsalva (RSOV) is an uncommon but clinically important feature. A 75-year-old man with progressive nocturnal dyspnea was diagnosed with severe aortic valve stenosis and moderate regurgitation. Preoperative computed tomographic scan revealed that the LCA originated from the RSOV separate from the right coronary artery and coursed into the ventricular septum. Because he did not experience any episodes of cardiac ischemia, isolated aortic valve replacement was performed using a 23-mm stented bioprosthesis without concomitant coronary revascularization. The postoperative course was free from coronary ischemia.
