ELECTIVE INTRA-AORTIC BALLOON PUMP IN PATIENTS UNDERGOING CORONARY ARTERY BYPASS GRAFT

Introduction:Preoperative electiveintra-aortic balloon pump (IABP)prompts improve result in helpless left ventricular function patients going throughcoronary artery bypass graft (CABG).The aim of this work was to assess the efficacy of preoperative intra-aortic balloon pump treatment on postoperative cardiac performance, morbidity and mortality.

Method:a prospective, cohort study was conducted on 40 patients with preoperative left ventricular ejection fraction< 40%, who went throughcoronary artery bypass graft. These patients were divided preoperatively into two groups:Group I (N.=20) received intraaortic balloon pump insertion 1-2 hours prior to aortic cross clamp.Group II (N.= 20) control group who did not receive intra-aortic balloon pump preoperatively.

Results:Both group were matched regarding age, sex distribution and body surface area,mean cardiac index in group I wassignificantly higher(2.5± 0.21 vs. 2±0.32) (P<0.0001). The mean cardiopulmonary bypass time in group I was significantly less (72.56± 21.62 vs. 86.68±20.57) (P=0.04).The ventilation time (hours) and total intensive care unit stay (days) were significantly less in group I (p<0.0001).

Conclusion: poor left ventricular function patients going through coronary artery bypass grafting possibly need perioperative intra-aortic balloon pump support to diminish morbidity and mortality.
