Abstract:
Congenital quadricuspid aortic valve is rare, which may be a cause of sever aortic regurgitation. We report a case of a 55-year-old man who had severe aortic regurgitation with congenital quadricuspid aortic valve. Preoperative aortography showed severe aortic regurgitation. Preoperative trans-esophageal echocardiography revealed abnormal quadricuspid aortic valve. We performed minimal invasive aortic valve replacement with SJM # 21 mm HP prosthetic valve through the limited upper sternotomy. Skin incision was 9 cm. Aortic cross-clamping time was 92 min, cardiopulmonary bypass time was 108 min. At the operation, a quadricuspid valve with three equal cusps and one small cusp was noted. The postoperative course was excellent and he discharged 8 days after the operation.
