摘要: Objectives To report clinical, angiographic characteristics, outcomes, and predictors of unsuccessful procedures in patients who underwent chronic total occlusion (CTO) percutaneous coronary interventions (PCI) Latin America. Background CTO PCI has been increasingly performed worldwide, but there is a lack information this region. Methods An international multicenter registry was developed to collect data on centers Patient, angiographic, procedural outcome were evaluated. Predictors assessed by multivariable analysis. Results We have included related 1,040 PCIs seven countries America (Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Puerto Rico). The mean age 64 ± 10 years, mainly for angina control (81%) or treatment large ischemic area (30%). Overall technical success rate 82.5%, it achieved with antegrade wire escalation 81%, dissection/re-entry 8% retrograde techniques 11% the successful procedures. Multivariable analysis identified moderate/severe calcification, blunt proximal cap previous attempt as independent In-hospital major adverse cardiovascular events (MACE) occurred 3.1% cases, death 1% cardiac tamponade 0.9% CONCLUSIONS: ischemia relief. Procedures associated above 80% low incidence MACE. similar those previously reported literature.
