Previous studies have shown that successful recanalization by stent implantation of a chronic total coronary occlusion (CTO) is associated with an improved clinical outcome. However, most of these studies have used first-generation stents and dated regimens of antithrombotic therapy.


We retrospectively investigated the short- and long-term clinical results of current techniques of percutaneous revascularization in 126 consecutive patients with CTO who underwent successful implantation of a new-generation bare metal stent and dual antiplatelet therapy.


There were neither in-hospital deaths nor subacute stent thrombosis; periprocedural acute myocardial infarction occurred in 6 (2.3%) patients; 25 (20%) late major events were observed during a mean follow-up of 19 +/- 10 months: one sudden death, two myocardial infarctions, and 22 cases of target vessel revascularization. Length of CTO > 24 mm (odds ratio = 1.06, p < 0.0245) and final minimal lumen diameter < or = 2.5 mm (odds ratio = 0.224, p < 0.01) were identified as independent predictors of late events.


The results of current practice of stenting of CTO are encouraging. Only angiographic variables are predictive of long-term clinical outcome.
