'Obstruction alternans' of a Sorin tilting disc prosthetic mitral valve: a case of emergency action.
We present a patient with a history of a Sorin tilting disc prosthetic mitral valve implanted 20 years ago who developed acute dyspnoea. Echocardiogram revealed a unique pattern of 'obstruction alternans' of mitral valve prosthesis due to pannus formation. We emphasize the need for urgent surgical treatment of this potentially fatal complication.
