[Coronary artery revascularization without cardiopulmonary bypass].
OBJECTIVE
We sought to report our recent experience with off-pump coronary artery revascularization.


METHODS
Between July 1998 and July 2002, 80 off-pump beating heart operations were performed at Vilnius University Hospital Heart Surgery Clinic, representing 4.05% of all coronary artery revascularization. This cohort of patients was compared with 241 patients operated on with cardiopulmonary by pass.


RESULTS
Mean age and preoperative risk factors were comparable for the two groups. On average, 2.02+/-0.86 and 4.09+/-1.09 grafts per patient were completed in the beating and cardiopulmonary bypass groups, respectively. Operation time was shorter in the beating heart group (169+/-41 vs. 215+/-59 minutes). Similarly, the need for transfusion was significantly smaller in the beating heart group (beating heart operations, 10%; cardiopulmonary bypass, 28%; p<0.001).


CONCLUSIONS
In majority of patients, off-pump coronary artery revascularization is an acceptable alternative to conventional operations with good results.
