, , 488-491. Experience of valve replacement with the Beall compressed Teflon disc valve in 59 patients confirms that the incidence of clinically significant late red cell destruction is high. An apparently previously unrecorded high incidence of early haemolysis, so severe in one patient as to be directly the cause of death, is reported. In 29 patients there was massive haemolysis in early convalescence, not recognized in urine from some hours after the end of bypass and never encountered with other designs of prosthetic valve or homograft valve.
488 - 491页。对59例患者使用比尔压缩聚四氟乙烯盘状瓣膜进行瓣膜置换的经验证实，临床上显著的晚期红细胞破坏发生率很高。据报道，早期溶血的发生率明显很高，此前显然未被记录，在一名患者中严重到直接导致死亡。在29例患者中，早期恢复期出现大量溶血，在体外循环结束后数小时的尿液中未被发现，在其他人工瓣膜或同种异体移植瓣膜设计中从未遇到过这种情况。
