[Successful mitral valve replacement in multiple organ failure due to mechanical hemolytic anemia after mitral valve...

An 18-year-old man suffered multiple organ failure due to hemolytic anemia after mitral valve repair. He was admitted with mitral regurgitation (MR) and mitral valve repair was performed. However, after 3 days of the operation, he developed hemolytic anemia and heart murmur. A reoperation of mitral valve replacement was performed because of progressing heart failure with renal and liver dysfunction. The operative findings revealed a rupture in the choldae with dislocation of the C-E ring. The MR flow and dislocated ring are suspected to be the cause of the hemolysis. After the reoperation, the hemolysis and general condition were immediately improved. The indication of this reoperation should be carefully decided. In this case of multiple organ failure following mitral valve repair, reoperation of mitral valve replacement was successful.
