Use of Intra-Aortic Balloon Pump During Coronary Artery Bypass Graft Surgery. Current Questions and Few Answers.

Abstract

The intra-aortic balloon pump (IABP) is used to prevent complications after coronary artery bypass grafting (CABG) surgery; although some results are controversial nowadays even contradictory. A new article on this field is published in this edition and shows that the risk factors for in-hospital mortality are the preoperative plasma creatinine level and cardiopulmonary bypass time in 177 patients. About the prophylactic use of the IABP regarding mortality the results reflected so far in meta-analyses have been highly contradictory between them, and the risk factors associated with it have been several and different. This lack of evidence has resulted in the continued variation of IABP use in these procedures. A large, multicenter RCT is certainly required to take the next step towards more definitive evidence, either for or against, the use of IABP in high-risk CABG. Until then, the unanswered questions regarding this topic will remain.

Analysis of Intra-Aortic Balloon Performance in Open-Heart Surgery

“…IABP use in various operations has continued to vary as a result of the lack of supporting data. [19] The majority of studies have shown a promising survival benefit for CAD patients receiving surgical therapy. However, it is claimed that low cardiac output syndrome as well as mortality in CABG are predicted by significant LV dysfunction (ejection fraction 35%) [20].…”
