A 80-year-old man presented to our hospital complaining exertional dyspnea. He was diagnosed with combined aortic valve regurgitation and stenosis due to quadricuspid aortic valve. The patient had no other cardiovascular anomaly. We performed aortic valve replacement( AVR) using minimally invasive cardiac surgery( MICS) approach. Four cusps were equal in size. Postoperative course was uneventful. AVR using MICS approach for quadricuspid aortic valve is extremely rare. In endoscopic surgery, the anatomical features of quadricuspid aortic valve can be more precisely understood, which may help in avoiding complications such as damage to the coronary ostia or the conduction system.
