title: [Surgical treatment of coronary sinus orifice atresia; report of a case].
abstract: 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.
