Percutaneous coronary intervention for chronic total occlusion in octogenarians: a propensity score study.

Feasibility and efficacy of complex percutaneous coronary intervention (PCI) in the elderly, a more frail population due to more comorbidities is incompletely understood. We therefore set out to compare success and complication rate of PCI for chronic total occlusion (CTO) in octogenarians, in comparison to non-octogenarians. Data from 267 patients (58 patients over 80 years of age and 209 under 80 years of age) who had undergone CTO PCI were analyzed.
