ABSTRACT
A 47-year-old man, having undergone mitral valve replacement in another hospital 9 years ago, suffered from sudden dyspnea and was transferred to our hospital immediately. On admission, disturbance of consciousness, severe dyspnea, marked hypotension (60/40) and hypo-oxygenation were noted. Under assisted ventilation with endotracheal intubation, diagnosis was confirmed by chest X-ray. The patient was transferred to the operation room after initiation of percutaneous cardiopulmonary support (PCPS). The emergency re-operation was started 7 hours after the onset of the symptoms. Left atriotomy was performed following total cardiopulmonary bypass and cardioplegic solution infusion. The pyrolite disc and the minor strut were missing and could not be found in the cardiac cavity. The fractured prosthesis was removed and replaced with a 29mm Carbomedics prosthesis. He was weaned from cardiopulmonary bypass with large doses of pressor amines. The disc and the strut were removed from the abdominal aorta and right deep femoral artery respectively 4 weeks after re-MVR surgery. The patient was discharged after 8 weeks' admission, and has been doing well so far. Although it is obvious that prompt diagnosis and early operation to replace the fractured prosthesis are essential for patient survival, percutaneous cardio-pulmonary support is helpful to maintain patient's hemodynamics during rediagnosis and preparation for surgery.
