title: Thrombosis of mechanical mitral valve prosthesis.
abstract: Obstruction of mechanical valve prostheses is a rare but potentially lethal complication following valve replacement surgery. Identifying the etiology and differentiation between thrombus, pannus, and vegetation obstructing the valve prosthesis can pose a diagnostic challenge. We report a patient who had an acute cerebral hemorrhage, developed a progressive mass lesion obstructing his mechanical mitral valve, and discuss contemporary diagnostic and management strategies.
