A 44-year-old female with left to right shunt and persistent left superior vena cava (PLSVC) suspected of unroofed coronary sinus defect with patent right SVC and innominate vein was treated surgically. PLSVC was ligated and coronary sinus ostium was closed with a EPTFE patch. Roof defect of coronary sinus was left open and allowed the coronary venous blood to drain into the left atrium. Patient recovered well and post-operative cardiac catheterization revealed no significant right to left shunt nor desaturation of arterial blood. In the correction of unroofed coronary sinus defect and PLSVC and no other intra-cardiac defect, ligation of PLSVC and closure of coronary sinus ostium was simple and effective, although it was not anatomically corrected.
一名44岁女性，存在左向右分流及持续性左上腔静脉（PLSVC），怀疑有无顶冠状静脉窦缺损伴右无名静脉及上腔静脉通畅，接受了手术治疗。结扎PLSVC，并用聚四氟乙烯补片封闭冠状静脉窦口。冠状静脉窦顶缺损保持开放，使冠状静脉血流入左心房。患者恢复良好，术后心导管检查显示无明显的右向左分流，动脉血也未出现氧饱和度降低。在矫正无顶冠状静脉窦缺损和PLSVC且无其他心内缺损时，结扎PLSVC并封闭冠状静脉窦口虽未进行解剖学矫正，但操作简单且有效。
