Abstract

A 17-year-old male patient was referred with symptoms of dyspnea. Multi-detector computerized tomography (MDCT) and echocardiography evaluation revealed quadricuspid aortic and pulmonary valves, an atrial septal defect (ASD), and pulmonary stenosis. We closed the ASD using a bovine patch and performed a commissurotomy of the pulmonary valve. Quadricuspid semilunar valves are very rare congenital abnormalities that are reported to occur nine times more frequently in the pulmonic valve than in the aortic valve. According to the Hurwitz and Roberts classification, the aortic valve was type A, and the pulmonic valve was type B. The aortic valve had normal function, but the pulmonic valve was stenotic and had abnormal function. (Korean J Thorac Cardiovasc Surg 2009;42:361-363)

Keywords: 1. Valve disease, 2. Pulmonary valve, stenosis, 3. Heart valve, abnormalities
