Does mitral valve replacement resolve intractable hemolytic anemia after mitral valve repair?
Mitral valve replacement can effectively resolve intractable hemolytic anemia caused by regurgitant jet collision into the annuloplasty ring after mitral valve repair.
Although hemolytic anemia after mitral valve replacement (MVR) is well recognized, hemolytic anemia associated with mitral valve repair is an uncommon condition. Furthermore, persistent and severe hemolytic anemia despite of medical treatment subsequently requiring reoperation is extremely rare. We here report three cases of intractable hemolytic anemia after mitral valve repair leading to MVR. Collision of regurgitant jet into the annuloplasty ring was the speculated mechanism of hemolysis in all cases. After MVR, all of them experienced immediate resolution of the hemolytic anemia.
