We report a case of a 69-year-old man with coronary sinus orifice atresia incidentally found during mitral and tricuspid valve operation in. Preoperatively, a patent left superior vena cava was noted. An abnormal opening of the coronary sinus was recognized in the inter-atrial septum of the left atrium near the postero-medial commissure of the mitral valve. The coronary sinus was absent in the right atrium. A coronary sinus was created by resecting the inter-atrial septum of the right atrium, and the abnormal opening of the coronary sinus at the left atrium was closed with an autologus pericardial patch. Tricuspid annuloplasty was performed with a 30 mm MC3 ring. Postoperative coronary sinus flow was confirmed normal by enhanced computed tomography (CT). Preoperative recognition of this rare disease is important, especially when the surgical candidate has a patent left superior vena cava.
我们报告一例69岁男性，在二尖瓣和三尖瓣手术中偶然发现冠状动脉窦口闭锁。术前，发现左上腔静脉通畅。在二尖瓣后内侧连合附近的左心房房间隔处发现冠状动脉窦异常开口。右心房未见冠状动脉窦。通过切除右心房房间隔建立冠状动脉窦，并使用自体心包补片封闭左心房冠状动脉窦的异常开口。使用30mm MC3环进行三尖瓣成形术。术后增强计算机断层扫描（CT）证实冠状动脉窦血流正常。术前识别这种罕见疾病很重要，尤其是当手术候选者存在左上腔静脉通畅时。
