After examining 100 hearts belonging to subjects who at the time of death had no record of coronariopathy, the presence of anastomoses between the 2 coronary systems was confirmed in 96% of the cases. Intramyocardial anastomoses located in the Crista supraventricularis accounted for 76% of the cases, 4 main types are described. The fact that crestal anastomoses always connect both coronary systems (even in cases of left dominance) is their most outstanding characteristic. The possible usefulness of this type of anastomoses was finally discussed. It was suggested that they might serve as a safety mechanism which would join areas severely affected by arteriosclerosis to others not so seriously damaged.
在检查了100颗属于死亡时无冠状动脉病变记录的受试者的心脏后，在96%的病例中证实了两个冠状动脉系统之间存在吻合支。位于室上嵴的心肌内吻合支占病例的76%，描述了4种主要类型。嵴部吻合支总是连接两个冠状动脉系统（即使在左优势型病例中）这一事实是其最突出的特征。最后讨论了这种类型吻合支可能的作用。有人提出，它们可能作为一种安全机制，将受动脉硬化严重影响的区域与其他受损不那么严重的区域连接起来。
