A single coronary artery, arising from the left sinus of Valsalva, associated with a bicuspid aortic valve and annuloaortic ectasia, is very rare. We report on a surgical case of bicuspid aortic valve regurgitation, annuloaortic ectasia, and dilation of the ascending aorta to the aortic arch in a patient with a single coronary artery. We successfully performed aortic root replacement with reimplantation of the single coronary artery and total arch replacement. The reimplantation of the coronary orifice required particular attention. Postoperative CT demonstrated the expected contours from the aortic annulus to the aortic arch with a patent implanted coronary artery.
一条源于左冠状动脉窦的单一冠状动脉，合并二叶式主动脉瓣及主动脉瓣环扩张，极为罕见。我们报告了一例单一冠状动脉患者，该患者患有二叶式主动脉瓣反流、主动脉瓣环扩张以及升主动脉至主动脉弓扩张，接受了外科手术治疗。我们成功实施了主动脉根部置换并重新植入单一冠状动脉，以及全弓置换。冠状动脉口的重新植入需要特别关注。术后CT显示从主动脉瓣环到主动脉弓的轮廓符合预期，植入的冠状动脉通畅。
