MECHANICAL ASSIST CIRCULATION FOR SEVERE HEART FAILURE AFTER OPEN HEART SURGERY AND NON-SURGICAL CARDIOGENIC SHOCK

Abstract

63 patients were performed circulatory support with mechanical assist circulation in the past 12 years. Survival ratewas 7.5% (3/40) in the veno-arterial bypass (VAB) support, 37.5% (3/8) in theleft atrioarterial support (AAB), 42.9% (3/7) in the VAB+AAB support, and 37.5% (3/8) in the ventricular assist device (VAD) support. Percutaneous cardiopulmonary support (PCPS) was performed on 6 patients (AAB:4, VAB:2) with cardiac arrest (4 pts) and non-surgical cardiogenic shock (2 pts). One patient was survived and two patients were recovered from shock and surgery was performed, one patient with cardiac arrest due to dilative cardiomyopathy was sequentially supported by VAD for bridge to heart transplantation. In conclusion, percutaneous AAB using transseptal puncture permits rapid start of left heart bypass support, thus can be an effective alternative for non-surgical cardiogenic shock patients.
