Severe Intermittent Transvalvular Mitral Valve Regurgitation: Serious Complication of Mitral Valve Replacement With Subvalvular Preservation.

ABSTRACT

Mitral valve replacement with subvalvular preservation is a favorable technique to protect left ventricular function and improve long-term survival. However, complications of the procedure should be considered. We report the case of a patient with a history of prosthetic mitral valve replacement with severe intermittent transvalvular mitral regurgitation and reduced ejection fraction. (Level of Difficulty Advanced.).
