Routine Intracoronary Shunting in Multivessel Off-Pump Coronary Artery Bypass: A Retrospective Review of in-Hospital Outcomes in 550 Consecutive Cases
Background: Since 1999 our institution has adopted off-pump coronary artery bypass grafting (OPCABG) for treating the majority of our patients. In the year 2001, 96% of our isolated coronary bypass procedures were performed on the beating heart. Routine use of intracoronary shunts in OPCABG has been a controversial topic. We use routine intracoronary shunting in all cases to maintain distal perfusion and to help achieve hemostasis.
Methods: We reviewed the first 550 OPCABG procedures performed at our institution (July 1998-December 2001) by 2 surgeons currently performing >95% of all coronary bypasses off-pump. All cases were completed with routine intracoronary shunting using Flo-Coil (Guidant, Santa Clara, CA, USA) or Flo-Thru (Bio-Vascular, St Paul, MN, USA) shunts. The mean number of grafts was 3.7. (range, 1-8). In-hospital outcomes in this series of patients were compared to outcomes in 485 patients operated on by the same 2 surgeons using traditional cardiopulmonary bypass (CPB) and aortic cross-clamping prior to adopting routine OPCABG. Statistical significance was calculated using Pearson chi-square analysis and reported for P values of <.05.
Results: The rates of occurrence of postoperative cardiovascular accident, atrial fibrillation, prolonged ventilator time, renal failure, and blood product use and the length of postoperative stay were significantly less in the off-pump group (P < .05). Predicted risk of mortality, observed mortality, and perioperative myocardial infarction rates were not significantly different in the 2 groups (P < .05). The conversion rate was 3.1%.
Conclusion: We conclude that routine intracoronary shunting in OPCABG is a safe technique that is associated
