| Abstract: | AIMS: Reevaluation of clinical and angiographic predictors for percutaneous recanalization of coronary chronic total occlusion (CTO) using current techniques with conventional PTCA wires and balloons. METHODS AND RESULTS: We studied 253 consecutive patients with 283 lesions who underwent attempted PTCA of CTO (mean time since occlusion 33 months, range 3-150 month). Immediate procedural success rate was 84.8% (95% CI = 80.3%-88.6%). Multiple clinical and angiographic characteristics were evaluated as possible predictors of success/failure. Multiple logistic regression analysis revealed that a tapered morphology (P < 0.001, OR = 6.1; 95% CI = 2.1-18.2),
