Off-pump coronary artery bypass
(OPCAB) has recently increased in popularity, but the long-term
results are still unknown. We evaluated the mid-term results
of OPCAB surgery using multi-slice computed tomography (MSCT),
which is a non-invasive postoperative evaluation method. Thirty-one
consecutive patients who underwent OPCAB surgery at least 2 years
prior to the study were selected. The age was 50 to 79 years
(66.9±6.5) and the ratio of men to women was 26: 5. Coronary
angiography was performed in all patients at 2 weeks postoperatively.
The follow-up was complete, and mean follow-up was 30.9 months.
There were no hospital deaths and 1 non-cardiac late death. The
graft patency rate in coronary angiography was left internal
thoracic artery (LITA) 30/30 (100%), right internal thoracic
artery (RITA) 2/2(100%), radial artery (RA) 14/15(93%), saphenous
vein graft (SVG) 15/17(88%). No graft became occluded on MSCT
study and all patients have been angina-free during the follow-up
period. We suggest that OPCAB is feasible in most patients with
good patency and low mortality. MSCT is an effective follow up
method for the morphological findings and non-invasive quantitative
evaluation of the bypass grafts.
