Magnetic resonance imaging, Quadricuspid aortic valve, Transesophageal echocardiography
A 64-year-old asymptomatic woman with quadricuspid aortic valve, a rare congenital malformation, is described here. The literature contains few reports of asymptomatic cases. Three cusps of equal size and a smaller accessory cusp were found when transesophageal echocardiography and magnetic resonance imaging were used to closely examine the aortic valve of the present patient, and moderate aortic regurgitation was detected at the center of the four cusps. No other cardiac anomaly was detected. Because sudden death is a serious complication of quadricuspid aortic valve, one should make the most of noninvasive tools such as transesophageal echocardiography and magnetic resonanca imaging, even in asymptomatic patients.
