Two cases of left ventricular-right atrial shunts inadvertently produced during aortic valve replacement are described. It is surprising that this complication is not more prevalent considering the close proximity of the aortic and mitral valves to the atrioventricular portion of the membranous septum. A left-to-right shunt should be a consideration in patients who fail to improve following aortic valve surgery, especially if the valve and subaortic region were heavily calcified or septal trauma occurred during the surgical procedure.
本文描述了两例在主动脉瓣置换术中意外产生左心室-右心房分流的病例。考虑到主动脉瓣和二尖瓣与膜性间隔房室部分的紧密相邻关系，这种并发症未更普遍发生着实令人惊讶。对于主动脉瓣手术后病情未改善的患者，尤其是瓣膜及主动脉下区域严重钙化或手术过程中发生间隔创伤的患者，应考虑存在左向右分流的情况。
