Percutaneous Cardiopulmonary Bypass for Cardiogenic Shock

Abstract

Percutaneous cardiopulmonary bypass was performed in 9 patients who developed cardiogenic shock. Of these patients, 5 were postoperative patients who developed cardiogenic shock on the day of operation. In 3 of these patients, intraaortic balloon pump was used in addition to percutaneous cardiopulmonary bypass. Two patients required percutaneous cardiopulmonary bypass in the cardiac catheterization laboratory for cardiogenic shock during angioplasty, and 2 other patients developed cardiogenic shock secondary to acute anterior wall myocardial infarction. Cardiopulmonary bypass was initiated with 18F femoral arterial and venous cannulae. Flow rates between 2.5 and 4.5 l/min and a mean blood pressure equal to or greater than 60mmHg were achieved. Of 5 postoperative patients, 3 survived and 2 died. Two patients who crashed during angioplasty were managed with emergency coronary artery bypass grafting, and both survived. Of 2 patients who developed cardiogenic shock following acute anterior wall myocardial infarction, 1 survived and 1 died. The surviving 6 patients were followed up for a mean period of 8 months. Five patients were in New York Heart Association Functional Class I, and 1 patient was in Class II.
