Mortality Predictors for Intra Aortic Balloon Pump Support after Cardiac Surgery

Objectives: Mechanical circulatory assistance is frequently needed to support the failing heart. The aim of this study was to determine perioperative prognostic factors for hospital mortality in patients undergoing open heart surgery who required intra-aortic balloon pump support Methods: 202 patients requiring IABP support were analyzed over an 11 year period from which 117 survived the 30 days follow-up. The male to female ration was 115/87. Perioperative risk factors such as age, weight, underlying diseases, ejection fraction, ventricular aneurysm, and cardiopulmonary bypass and cross clamp time were recorded and analyzed. Results: The overall operative mortality was 42.1%. The early mortality was related to older age and prolonged CPB time. The patients’ age, gender, weight, preoperative ejection fraction, ventricular aneurysm and left main coronary stenosis didn’t affect the mortality rate. Conclusions: IABP represents a safe option of supporting the failing heart in the older patients undergoing shorter cardiac surgeries.
