New Presentation of Hemolysis After Papillary Muscles Approximation for Mitral Valve Repair

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.
