A bstract Background Repair of unroofed coronary sinus defect in the presence of left superior vena cava is challenging and requires prosthetic graft material to redirect flow to the right atrium. This may potentially cause a supra‐mitral gradient or pulmonary venous obstruction. Methods Three patients with unroofed coronary sinus in the presence of a left superior vena cava (LSVC) underwent modified cavo‐atrial anastomosis (Warden technique) to achieve reimplantation of the LSVC in a retro‐aortic fashion to the right atrial appendage. Results Three patients recovered well with no evidence of an intracardiac shunt. Postoperative echocardiography demonstrated normal venous flows in the LSVC. Conclusion This modified technique offers correction of this systemic venous anomaly without the need for any additional graft material. doi: 10.1111/jocs.12684 (J Card Surg 2016;31:103–105)
