Key result
Mitral valve replacement with a bioprosthesis successfully resolved persistent severe hemolysis following previous mitral valve repair in a patient with a severely calcified annulus.
Mitral valve replacement with a bioprosthesis, retaining the posterior annuloplasty ring and preserving chordae, successfully resolved severe hemolysis following mitral valve repair in a patient with severe annular calcification.
May inform management of refractory post-repair hemolysis in calcified annuli; leaves open generalizability pending larger series.
We present a patient with persistent severe hemolysis following mitral valve repair which resolved after valve replacement with bioprosthesis. The posterior portion of the annuloplasty ring was retained due to severe calcifications of the posterior mitral valve annulus. All chordae were preserved to avoid disruption of the mitral annulus.
