Of 11 patients who underwent emergency resuscitation from cardiac arrest using a system of percutaneous cardiopulmonary support (CPS), two (18%) were long-term survivors. Percutaneous cardiopulmonary support was instituted without complication in all patients, with flows ranging from 1.8 to 5.5 L/min; the average duration of support was 304.3 min. All four patients who underwent emergency surgery (two coronary revascularization, one mitral valve revascularization, one mitral valve replacement with coronary revascularization, and one primary left ventricular assist device insertion) died. ⋯ Cardiopulmonary support can be instituted, resulting in excellent stabilization in patients with cardiac arrest. Survivors tended to be young and not have atherosclerotic cardiovascular disease (ASCVD) as their primary diagnosis. Neither length of cardiac arrest before CPS nor time on support correlated with a poor outcome.(ABSTRACT TRUNCATED AT 250 WORDS)

Emergency cardiopulmonary support (CPS) was instituted in 53 consecutive patients for acute life threatening pathologies. Indications for CPS deployment were: cardiac arrest, 60% (n = 32); cardiogenic shock, 20.4% (n = 11), supported angioplasty, 13% (n = 7); and adult respiratory distress syndrome, 5.6% (n = 3). Cardiopulmonary support was successfully deployed in 51 of the 53 patients (96%), resulting in a mean blood pressure greater than or equal to 60 mmHg, CO greater than or equal to 3-5 L/min, and partial pressure of oxygen greater than or equal to 100 mmHg, with venous oxygen saturation greater than or equal to 60%. ⋯ The overall survival using the CPS system is 59% short-term (greater than 24 hrs.), and 33% long-term (greater than 30 days). In conclusion, the CPS system is a potent and effective resuscitative tool. It requires transfer to other treatment modalities for survival in most cases.
