Abstract :

Background:  Off-pump coronary artery bypass graft (CABG) using arterial conduits has been performed in our institute to improve postoperative outcomes.  In this study, we analyzed the outcomes in patients who underwent total arterial off-pump CABG.

Methods:  Between 03/01/1999 and 7/30/2002, a total of 349 patients (263 males and 86 females, mean age of 66.3 � 9.5) underwent isolated off-pump CABG using arterial grafts.  Perioperative and follow-up data were entered into a structured database, and their results were analyzed.

Results:  The mean number of bypass grafts was 3.5 � 1.1.  There was no intraoperative conversion from off-pump to on-pump surgery.  The mean intubation period, ICU stay, and postoperative hospital stay were 9.0 hours, 2.3 days, and 12.7 days, respectively.  There were  4 (1.1%) hospital deaths.   Postoperative myocardial infarction was observed in 4 (1.1%), postoperative congestive heart failure in 5 (1.4%), stroke in 7 (2.0%) and mediastinitis in 5 (1.4%).  During the follow-up period of 2.2 � 0.9 years, there were 3 deaths and 13 cardiac events.  The actuarial 3-year survival rate was 99.7% and the actuarial event-free rate was 95.9%.

Conclusion:  Off-pump CABG using total arterial grafts provides good clinical outcomes.

Key words: coronary artery disease, off-pump bypass, prospective study, follow-up study
