				        	A 63-year-old man was admitted due to acute congestive heart failure. Transesophageal echocardiography demonstrated quadricuspid aortic valve malformation with concomitant severe aortic regurgitation. The valve was replaced by a 21mm Edward-MIRA and the postoperative course was uneventful. Although quadricuspid aortic valve is a rare anomaly, its potential for severe valve failure in adulthood should not be neglected.
