. , , 627-630. . Three patients are described. In each, a diseased aortic valve was replaced by a Björk-Shiley valve prosthesis. For different reasons, ventricular fibrillation occurred when the patient was still on cardiopulmonary bypass. In these circumstances, a massive leak occurred through the valve and caused overdistension of the left ventricle. Subsequent examination of the valves in the laboratory showed that, under the conditions described above, there was a leakage equal in volume to half the forward flow.
本文描述了3例患者。每例患者均用Björk-Shiley瓣膜假体替换病变的主动脉瓣。由于不同原因，患者仍在体外循环时发生心室颤动。在这种情况下，瓣膜出现大量漏血，导致左心室过度扩张。随后在实验室对瓣膜进行检查发现，在上述条件下，漏血量相当于前向血流量的一半。 （原文出处为某文献，页码627 - 630）
