Hemolysis is a well-recognized complication after prosthetic valve replacement, especially with perivalvular leaks. Hemolytic anemia associated with mitral valve (MV) repair is less common. We report the case of a young man with severe hemolytic anemia caused by turbulence of blood flow through a very small quadrangle orifice due to early failure of MV repair. The patient underwent redo MV biologic prosthesis replacement and tricuspid valve annuloplasty. The hemolysis completely disappeared few months later. In this case, we describe a new presentation of mechanical hemolysis due to early failure of MV repair that has not been described in the literature.
溶血是人工瓣膜置换术后一种公认的并发症，尤其是伴有瓣周漏时。与二尖瓣（MV）修复相关的溶血性贫血较少见。我们报告了一例年轻男性病例，其因MV修复早期失败导致血流通过非常小的四边形孔口产生湍流，进而引发严重溶血性贫血。该患者接受了二尖瓣生物假体再次置换及三尖瓣环成形术。几个月后溶血完全消失。在本病例中，我们描述了一种因MV修复早期失败导致的机械性溶血新表现，这在文献中尚未见报道。
