A hitherto undescribed cause of prosthetic mitral valve obstruction
AA Jones, JB Otis, GF Fletcher and WC Roberts
A case is described in which severe prosthetic mitral valve obstruction was
produced by entanglement of sutures across the central axis of the
prosthesis on its ventricular side. The entangled sutures prevented the
tilting disc occluder from falling into the left ventricular cavity during
ventricular diastole.
