A right coronary artery originating from the left coronary sinus and traversing anteriorly is thought to be one of the contraindications for a Konno aortoventriculoplasty in congenital aortic stenosis because this procedure necessitates incision of the right ventricular outflow tract. The case of a 5-year-old girl with congenital aortic stenosis associated with a single coronary artery, successfully treated surgically by the Konno procedure and right coronary artery reimplantation, is reported. Preoperatively there was a pressure gradient between the left ventricle and the ascending aorta of 109 mmHg, which disappeared postoperatively. A postoperative angiography showed a patent right coronary artery.
起源于左冠状窦并向前走行的右冠状动脉被认为是先天性主动脉瓣狭窄行Konno主动脉心室成形术的禁忌证之一，因为该手术需要切开右心室流出道。本文报道了一名5岁先天性主动脉瓣狭窄合并单支冠状动脉的女孩，通过Konno手术和右冠状动脉再植术成功接受手术治疗的病例。术前左心室与升主动脉之间的压力阶差为109 mmHg，术后消失。术后血管造影显示右冠状动脉通畅。
