Case Report

In September 1991 a 62-year-old female presented to our institute for replacement of a prosthetic mitral valve. She was cannulated for cardiopulmonary bypass via the right femoral artery with venous drainage through the inferior and superior vena cava. During rewarming there was a sudden drop in arterial blood pressure. After the cross clamp was removed the heart remained flaccid with no apparent perfusion of the coronary arteries. As a result of this, the diagnosis of retrograde aortic dissection was made and the ascending aorta was immediately cannulated. In spite of this action, severe metabolic acidosis, hyperkalemia and oliguria had developed. After two attempts to wean the patient off bypass and when maximal pharmacological support had failed, bypass was discontinued and the patient was pronounced dead.
Key words: retrograde aortic dissection / cardiopulmonary bypass / mitral valve replacement
