The location and size of the coronary sinus in hearts with atrioventricular septal defect were investigated in relation to the known disposition of the atrioventricular conduction axis. We examined the morphology in 40 hearts and supplemented this series with two other hearts that had been serially sectioned previously. The coronary sinus received drainage from a persistent left superior caval vein in 5 hearts. Six cases of 40 had malalignment of the septal structures relative to the crux of the heart. In these, the conduction axis was anticipated to course in the position where the inlet ventricular septum met the atrioventricular junction. The coronary sinus terminated in the left atrium in 4 hearts: 2 in the morphological series and 2 that were sectioned for histological studies. The sectioned hearts showed the atrioventricular conduction axis in the usual position for the defect, unrelated to the coronary sinus. The principle that the node and penetrating bundle are located at the intersection of the ventricular septum with the atrioventricular junction holds good despite the variability of the coronary sinus.
研究了患有房室间隔缺损的心脏中冠状窦的位置和大小，并将其与已知的房室传导轴的分布情况相关联。我们检查了40颗心脏的形态，并通过另外两颗先前已连续切片的心脏补充了该系列研究。5颗心脏的冠状窦接受来自持续左上腔静脉的引流。40例中有6例的间隔结构相对于心脏十字交叉处排列不齐。在这些病例中，预计传导轴会在流入道室间隔与房室交界处的位置走行。4颗心脏的冠状窦终止于左心房：形态学系列中有2颗，为组织学研究而切片的有2颗。切片的心脏显示房室传导轴处于该缺损的通常位置，与冠状窦无关。尽管冠状窦存在变异性，但结和穿入束位于室间隔与房室交界处的交叉点这一原则仍然成立。
