Abstract
Percutaneous cardiopulmonary support (PCPS) was instituted in 25 patients with acute circulatory failure. There were 16 male and 9 female patients ranging in age from 47 to 82 years. The causes of bypass initiation were acute myocardial infarction (12), post-infarction left ventricular rupture (4), Low output syndrome after coronary artery bypass grafting (4), ruptured thoracic aortic aneurysm (2), myocarditis (1), left ventricular rupture after mitral valve replacement (1), and iatrogenic right ventricular rupture (1). 14 of 25 patients underwent therapeutic interventions. The duration of support ranged from 0.25 to 64 (mean 22.3) hours. 16 patients weaned from PCPS and 11 were survived. In patients assisted within 24 hours, therapeutic interventions improved the survival rate. And some of patients assisted over 24 hours died of cardiac failure after weaned from PCPS. In conclusion, the use of PCPS for patients with acute circulatory failure achieved significant survival. To improve clinical results we should undergo therapeutic interventions as soon as possible during PCPS, and for patients assisted over 24 hours probably left heart bypass will be more effective.
