OBJECTIVES
Percutaneous coronary intervention (PCI) for chronic total occlusions (CTOs) is associated with lower rates of procedural success and higher complication rates compared with PCIs in non-CTO lesions. The purpose of this study was to analyze the relationship between lesion characteristics and procedural success rates and in-hospital outcomes after PCI for CTO with novel equipment.

STUDY DESIGN
We evaluated the prospectively entered data of 63 consecutive patients undergoing PCI for CTO at our institute between August 2009 and June 2012.

RESULTS
A total of 63 patients (mean age: 64±11, 71% male) with one CTO lesion each underwent PCI. There were 46 patients (mean age: 63±10, 70% male) in the CTO success group and 17 patients (mean age: 65±13, 76.5% male) in the CTO failure group. Successful revascularization was achieved in 73% of patients. We used antegrade approach in 61 cases and retrograde approach in 2 cases. Our predominant strategy was single-wire technique, which was used in 54 cases (85.7%), followed by parallel-wire technique in 7 cases (11.1%). Moderate-to-severe tortuosity (odds ratio [OR]: 9.732, 95% confidence interval [CI]: 1.783- 53.115, p=0.009) and occlusion duration (OR: 1.536, 95% CI: 1.178-2.001, p=0.002) were independent predictors of procedural failure in the multivariate analysis. No in-hospital major cardiac events occurred.

CONCLUSION
We have reported a study with a relatively high success rate of PCI with very low procedural and in-hospital complications. Moderate-to-severe tortuosity was observed as the most challenging problem despite the utilisation of novel equipment and techniques for CTO recanalization.
