<jats:p><jats:bold>Abstract: </jats:bold> Emergency percutaneous cardiopulmonary bypass support (PCPS) was instituted in 3 patients with acute myocardial infarction in cardiac arrest refractory to conventional resuscitation measures. All had severe double or triple vessel disease. Percutaneous transluminal coronary angioplasty (PTCA) was performed in 1 patient, and PTCA and directional coronary atherectomy (DCA) were performed in the other 2 patients on combined intraaortic balloon pumping (IABP) and PCPS. Flow rates of 2 to 5 L/min were achieved, with restoration of mean arterial pressure to more than 60 mm Hg during PCPS. The status of all patients was improved hemodynamically with PCPS. One patient died of hemorrhage during PCPS.</jats:p><jats:p>DCA was successfully performed in the other 2 patients, and PCPS and IABP was discontinued. Time on PCPS ranged from 10 h to 8 days. Time on IABP ranged from 10 days to 2 weeks. These 2 patients died of pneumonia or multiorgan failure after 1. 5 months. In conclusion, emergency PCPS is a powerful resuscitative tool that may stabilize the condition of patients in cardiac arrest to allow for definitive intervention.</jats:p>
