A 58-year-old man presented with severe aortic regurgitation(AR) with quadricuspid valve. Intraoperatively, the small accessory cusp was separated from non-coronary cusp( NCC). The NCC and small accessory cusp were sutured to obtain 1 competent cusp, aiming at an effective height of 8 mm. His AR was trivial at the postoperative 7th day.
