Abstract | BACKGROUND: Retrograde approach increases the success rate for percutaneous recanalization of complex chronic total occlusion (CTO) of coronary arteries.OBJECTIVES: The purpose of this study was to describe our initial experience of retrograde percutaneous coronary intervention for CTO program, focusing on its safety and feasibility, and long-term clinical follow-up.METHODS: The study was a single center retrospective registry which included a total of 40 patients, of 590 CTO treated patients (6.7%), between January 2008 and October 2011, who underwent retrograde approach for CTO recanalization.RESULTS: Mean occlusion duration was 37.8 ± 40.3 months. Overall success recanalization rate was 87.5% (35/40). Septal collaterals were used to access the occlusion in all cases (100%). Retrograde guidewire crossing of collateral channels was successful in 36/40 (90.0%) patients with success rate of CTO recanalization in these patients of 97.2%. Retrograde approach as the primary strategy was applied in 23/40 (57.5%) patients, retrograde approach immediately after antegrade failure attempt was performed in 8/40 (20.0%) patients, and retrograde approach as elective procedure, after previously failed antegrade attempt, was performed in 9/40 (22.5%) patients. The success rate of these strategies was: 87.0% (20/23 patients) for primary, 87.5% (7/8 patients) for retrograde immediately after antegrade failure, and 88.9% (8/9 patients) for retrograde after previous failed antegrade attempt, respectively. Total in-hospital major adverse cardiac events (MACE) rate was 5.0% (2 non-Q-wave myocardial infarctions). The MACE free survival at median follow-up of 20 months was 89% (95% CI: 78-100%).CONCLUSIONS: This study has demonstrated that adequate training and international proctorship for this complex and demanding technique is a necessity and prerequisite to achieve high overall success rates, with acceptable complication rates and excellent long-term survival rate. |
