Background. Dislocations of the heart required for exposure and construction of distal anastomoses often produce hemodynamic instability when performing coronary artery revascularization without using cardiopulmonary perfusion (OPCAB). We report our early experience with elective intraaortic balloon counterpulsation (IABP) to enable and facilitate selected high-risk patients to undergo OPCAB.

Methods. Sixteen high-risk patients undergoing multivessel OPCAB using elective IABP are reported. The patients were believed to be at increased risk because of the presence of severe proximal multivessel coronary artery obstruction, ventricular dysfunction, recent acute myocardial infarction, cardiomegaly–cardiomyopathy, and documented cerebral vascular disease. The presence of significant comorbid disease also made the avoidance of cardiopulmonary bypass desirable, if at all possible, in all patients.

Results. The IABP appeared to facilitate the intraoperative management of our series of patients. This was evidenced by improved hemodynamic stability and virtual elimination of the need for inotropic support during the dislocations of the heart needed for exposure and construction of distal anastomoses. There were no complications related to use of IABP. There was one death.

Conclusions. We believe this strategy to use IABP selectively can allow surgeons to safely extend the benefits of OPCAB procedures to high-risk patients and avoid dangerous hemodynamic instability that otherwise, often occurs.
