In-hospital and long-term outcomes after percutaneous coronary intervention for chronic total occlusion in elderly patients: A consecutive, prospective, single-centre study

Summary 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
