Does PCI of Chronic Total Occlusion Improve Survival?

Successful PCI-CTO was not associated with improved survival, as compared with failed PCI.

Percutaneous coronary intervention for chronic total occlusions (PCI-CTO) is increasingly performed despite safety concerns over radiation exposure, contrast use, and other complications. In this observational study of a large Korean registry of patients undergoing PCI-CTO, investigators compared 1004 stable patients with successful elective PCI-CTO receiving drug-eluting stents with 169 patients with failed PCI-CTO.

Successful procedures were associated with greater improvement in angina at the first follow-up visit. At a median follow-up of 4.6 years, all-cause mortality was not different between those with successful (8.0%) and those with failed (7.1%) PCI (multivariable adjusted hazard ratio, 1.04). Patients with failed PCI were more lik…
