A previously unrecorded cardiac anomaly is described. A defect existed in the lowest part of the atrial septum straddling the orifice of the inferior vena cava so that this vessel opened into both atria. There was an associated anomalous connexion of the right pulmonary veins to the right atrium. The septal defect was recognized only at necropsy. As in the case of a sinus venosus atrial defect, it is suggested that the fundamental embryological error responsible for the production of the rare defect here described is laevo-position of the sino-atrial orifice.
本文描述了一种此前未记录的心脏异常情况。房间隔最低部分存在一个缺损，横跨下腔静脉口，致使该血管开口于两个心房。同时存在右肺静脉与右心房的相关异常连接。该间隔缺损仅在尸检时被发现。与静脉窦型房间隔缺损的情况一样，本文认为导致此处所描述的这种罕见缺损的根本胚胎学错误是窦房口的左位。
