title: [Evaluation of preoperative intraaortic balloon pumping for high risk off-pump coronary artery bypass grafting].
abstract: We evaluated the effect of preoperative intraaortic balloon pumping (IABP) support in high risk patients undergoing off-pump coronary artery bypass grafting (OPCAB). Between November 1999 and December 2010, 65 high-risk patients underwent OPCAB with the support of IABP inserted preoperatively. High risks were considered as (1) left main coronary artery stem stenosis > or = 75%, (2) unstable angina requiring intravenous nitrates and heparin, (3) preoperative left ventricular ejection fraction < or = 30%, (4) bilateral carotid artery stenosis > or = 75%. There were no hospital deaths or cerebrovascular complications. During operations, hemodynamics was stable with the support of low dose catecholamines, and no patient needed conversion to on-pump coronary artery bypass grafting. All patients were able to be weaned from IABP within 3 days (mean 5.7 hours) after the operation and were extubated within 4 days (mean 11.5 hours) after the operation. One patient had a peripheral embolism which might be related to insertion of IABP (1.5%). Preoperative IABP in high-risk patients undergoing OPCAB was considered to be useful and safe.
