title: Entrapment of subvalvular mitral tissue causing intermittent failure of a St Jude mitral prosthesis.
abstract: Frequently portions of the mitral valve and sub-valvular apparatus are left intact during mitral valve replacement to help preserve left ventricular function. We describe a patient with paroxysmal congestive heart failure caused by intermittent entrapment of the subvalvular apparatus in the prosthesis, preventing complete valve closure.
