The St. Jude Medical prosthesis has become one of the most widely used mechanical heart valves because of its excellent haemodynamic function. Although subclinical haemolysis has been described with this prosthesis, there has only been a single report of frank haemolysis in the absence of a paravalvular leak. We report the occurrence of severe haemolysis in five patients following St Jude Medical prosthesis implantation, four of whom had combined aortic and mitral valve replacements. In no patient could the haemolysis be attributed either to a paravalvular leak or an obvious valve malfunction.
圣犹达医疗公司生产的人工心脏瓣膜因其出色的血流动力学功能，已成为使用最为广泛的机械心脏瓣膜之一。尽管曾有关于该人工心脏瓣膜出现亚临床溶血的报道，但仅有一例在不存在瓣周漏的情况下发生明显溶血的报告。我们报告了5例植入圣犹达医疗公司人工心脏瓣膜后出现严重溶血的病例，其中4例同时进行了主动脉瓣和二尖瓣置换术。所有患者的溶血均无法归因于瓣周漏或明显的瓣膜功能故障。
