[Outcome of percutaneous coronary intervention of graft occlusion post coronary artery bypass graft].
OBJECTIVE
To evaluate the feasibility and efficacy of percutaneous coronary intervention (PCI) for graft occlusion post coronary artery bypass graft (CABG).


METHODS
The clinical data of 135 post-CABG patients with bypass graft occlusion and angina pectoris symptoms admitted to our department between June 2003 and June 2007 were analyzed. The mean interval from CABG to index angiography was 33.8 +/- 23.5 months. Among 318 grafts, 29 left internal mammary artery (LIMA, 29/128, 22.7%) and 117 saphenous vein bypass grafts (117/188, 62.2%) were occluded. A total of 158 target lesions from these 146 vessels were treated with PCI. All target lesions were B2/C type lesion with 29.7% (47/158) chronic total occlusions.


RESULTS
A total of 310 DES were implanted. The total success rate of PCI procedure was 96. 3% (130/135), and lesion success rate was 96.8% (153/158). No major clinical complications occurred during peri-intervention period. All patients underwent PCI were followed at 12 month. Angiographic follow-up was obtained in 89 patients and the angiographic restenosis rate was 5.6% (5/89) in these patients. The major adverse cardiac events and target vessel revascularization rates were 5.4% (7/130) and 6.2% (8/130), respectively.


CONCLUSIONS
This study demonstrates that PCI procedure for graft occlusion post-CABG is feasible and safe and associated with a high procedure success rate and favorable long-term clinical and angiographic outcomes.
