This study was conducted to assess the determinants of the procedural success and long‐term clinical benefits of percutaneous transluminal balloon angioplasty (PTCA) of chronic total occlusion (CTO) in recent years. Two hundred and twenty‐six consecutive patients who underwent PTCA of CTO were divided into two groups according to the procedural success (n = 134) or failure (n = 92). Both groups were analyzed in terms of the initial success, predictors of procedural failure, and clinical outcome. The procedural success rate was noted to have improved to more than 70% since 1995. A multiple logistic regression analysis revealed that the presence of calcification, the length of the occlusion and the presence of multivessel disease were independent predictors of procedural failure. Cardiac death and the need for coronary surgery were significantly less frequent in patients with procedural success than in those with procedural failure. In properly selected cases, the success rate of PTCA of CTO is acceptable. Long‐term clinical benefit is suggested by the high rate of freedom from coronary surgery and the low cardiac death rate in the patients who underwent successful revascularization. Cathet.
