    Abstract:
    BACKGROUND: Elderly patients are increasingly referred for complex percutaneous coronary interventions (PCI), including recanalization of chronic total occlusion (CTO). AIMS: To assess the feasibility, safety and clinical benefits associated with CTO-PCI in elderly patients. METHODS: Consecutive patients (n=356) who underwent CTO-PCI in our institution between January 2008 and December 2011 were prospectively included. The short-term outcomes of CTO-PCI were assessed by comparing the rates of successful recanalization and postoperative complications in patients aged ≥ 75 years and those < 75 years. The clinical effect of successful recanalization was evaluated in a 20-month follow-up analysis in patients ≥ 75 years. RESULTS: Although patients ≥ 75 years (n = 93) had more complex coronary artery disease, the procedural success rate was similar to that in younger patients (78.2% vs. 74.3%, respectively; P = 0.41). Postoperative complications were more frequent in older patients (5.4% vs. 0.4%; P = 0.005). Major adverse cardiac event-free survival analysis at 20 months revealed that successful revascularization was indicative of a better prognosis in older patients (hazard ratio: 0.43, 95% confidence interval: 0.19-0.96; P = 0.039). CONCLUSION: Elderly patients have more complex coronary disease and are at a higher risk of postoperative complications. Nevertheless, we observed a similar success rate for CTO-PCI in elderly patients as for younger patients. Successful CTO recanalization improved the event-free survival rate at 20 months. Thus, CTO-PCI constitutes an alternative strategy for treating selected elderly patients.
