A large communication between coronary sinus and left atrium is a rare cardiac anomaly. Twenty-four cases from the literature and 2 of our own observations are presented. In most cases a considerable left-to-right shunt may exist on the atrial level that can be misinterpreted as an atrial septal defect. The anomaly may be isolated or in combination with an atrial septal defect or complex cardiac malformations. It is difficult to diagnose this abnormality by cardiac catheterization and even during surgery. Continuous oximetry during a fiberoptic catheter pull-back in the coronary sinus ensures the diagnosis in the case of atrial left-to-right shunt. The anatomy, hemodynamics, diagnostic procedures, and the therapy of the cases reported are discussed.
冠状窦与左心房之间的大交通是一种罕见的心脏异常。本文介绍了文献报道的24例以及我们自己观察到的2例。在大多数情况下，心房水平可能存在大量的左向右分流，这可能被误诊为房间隔缺损。该异常可能是孤立的，也可能与房间隔缺损或复杂的心脏畸形合并存在。通过心导管检查甚至在手术过程中都很难诊断这种异常。在冠状窦内进行光纤导管回撤时持续进行血氧饱和度测定可确保在存在心房左向右分流的情况下做出诊断。本文讨论了所报道病例的解剖结构、血流动力学、诊断方法及治疗。
