Hemolytic anemia following mitral valve repair and annular ring placement is uncommon compared with mitral valve replacement. A 60-year-old man, who had undergone mitral valve repair with a Duran ring, developed hemolytic anemia and needed a blood transfusion. Transesophageal echocardiography revealed a paravalvular mitral regurgitation jet colliding with the Duran ring. Most cases of severe hemolysis after mitral valve repair have undergone reoperation, but in the present case study, the hemolysis after mitral valve repair reduced without the need for reoperation, although the paravalvular mitral regurgitation jet continued to collide with the Duran ring.
与二尖瓣置换术相比，二尖瓣修复术和瓣环置入术后发生溶血性贫血并不常见。一名60岁男性，曾接受使用杜兰环的二尖瓣修复术，出现了溶血性贫血且需要输血。经食管超声心动图显示，瓣周二尖瓣反流束与杜兰环碰撞。二尖瓣修复术后发生严重溶血的大多数病例都接受了再次手术，但在本病例研究中，尽管瓣周二尖瓣反流束持续与杜兰环碰撞，但二尖瓣修复术后的溶血情况有所减轻，无需再次手术。
