Atrial septal defects can occur at various levels of the interatrial septum. Sinus venosus atrial septal defect (SVASD) results from abnormal resorption of the embryologic sinus venosus, and may be of the superior or inferior type. In this paper, we describe a 46-year-old man with inferior-type SVASD who presented with arrhythmias and dyspnea. Cardiac magnetic resonance and cardiac catheterization were useful in evaluating the anatomic/functional characteristics of inferior-type SVASD and distinguishing it from unroofed coronary sinus.
房间隔缺损可发生于房间隔的不同层面。静脉窦型房间隔缺损（SVASD）是由于胚胎静脉窦的异常吸收所致，可分为上腔型或下腔型。在本文中，我们描述了一名46岁患有下腔型SVASD的男性患者，其表现为心律失常和呼吸困难。心脏磁共振成像和心导管检查有助于评估下腔型SVASD的解剖/功能特征，并将其与冠状静脉窦未闭相鉴别。
