Left ventricular pseudoaneurysm secondary to recurrent mitral prosthetic valve endocarditis.

An 86-year-old man who had undergone two mitral valve replacements developed heart failure due to prosthetic valve infection and left ventricular pseudoaneurysm (LVPA). LVPA due to infective endocarditis is rare and caused by the abscess formation in the left ventricular myocardium. Infective endocarditis caused by enterococci requires attention to relapse.
