The objective of this study was to highlight the incidence and predictors of re-occlusion after successful recanalization of chronic total coronary occlusions. METHODS AND RESULTS: Following successful recanalization and stent implantation in 716 coronary lesions (665 patients) with chronic total occlusion, four hundred and five (56.6%) lesions (375 patients) underwent repeat angiography within 6 months. Restenosis (> or = 50% lumen narrowing) was observed in 151 (37.3%) lesions; forty-three (10.6%) of these lesions had complete re-occlusion and constituted the study population. In this group, final angiographic minimal lumen diameter (MLD) was 2.6 +/- 0.51 mm and final percent diameter stenosis was 18 +/- 11. Univariate analysis revealed significant correlation between re-occlusion and restenotic lesions, final balloon diameter, final percent diameter stenosis, final angiographic MLD, number of stents per lesion and total stent length. By multivariate analysis, the only independent predictor of re-occlusion was total stent length (OR = 1.46, 95% CI = 1.12-1.82; p = 0.0069). CONCLUSION: Re-occlusion occurs in about 11% of cases after stenting chronic total occlusion. The most important predictor of re-occlusion seems to be stent length. |
