The location, and morphology, of the superior sinus venosus interatrial communication remains contentious. As part of a clinical study, we examined anatomic specimens and echocardiograms so as to clarify the arrangement of the normal atrial septal structures, and compared them with the arrangement found in the superior sinus venosus defect. The pathognomonic diagnostic criterion in the abnormal hearts was overriding of the intact muscular rim of the oval fossa by the mouth of the superior caval vein. This muscular rim is, in reality, a tube of myocardium which encloses a core of extracardiac adipose tissue. Understanding of this anatomic conundrum clarifies the understanding of the structures of both the normal atrial septum and sinus venosus defects.
上腔静脉窦型房间隔交通的位置和形态仍存在争议。作为一项临床研究的一部分，我们检查了解剖标本和超声心动图，以阐明正常房间隔结构的排列，并将其与上腔静脉窦型缺损中的排列进行比较。异常心脏的特征性诊断标准是上腔静脉口覆盖卵圆窝完整的肌性边缘。实际上，这个肌性边缘是一个心肌管，其包绕着心外脂肪组织核心。对这一解剖难题的理解有助于明晰对正常房间隔和上腔静脉窦型缺损结构的认识。
