Long-term outcomes after revascularization in chronic total and non-total occluded coronary arteries: A regionwide cohort study.

Background: Understanding the prognostic impact of percutaneous coronary intervention (PCI) in chronic total occlusion (CTO) is crucial for patient management. Previous studies have primarily been studying prognostic impact of successful versus unsuccessful CTO PCI. This study investigated the prognostic impact of successful and unsuccessful percutaneous coronary intervention (PCI) of chronic total occluded coronary arteries (CTO) with non-CTO PCI as reference.

Chronic Total Occlusion is Not a Risk Factor for Mortality in Patients With Successful Percutaneous Coronary Intervention: A Cohort Study.

Background Fifteen percent of patients with coronary artery disease undergoing angiography have a chronic total occlusion (CTO). The current study aimed to investigate the long-term prognosis after successful and unsuccessful CTO percutaneous coronary intervention (PCI) compared with PCI for non-CTO lesions. Methods and Results The current study was designed as an observational, region-wide, register-based cohort study enrolling all patients undergoing PCI in the Central Region of Denmark in 2009 to 2019.

Early and long-term prognosis in patients with remaining chronic total occlusions after revascularization attempt. A cohort study from the SKEJ-CTO registry.

Objectives: The present study aimed to compare safety and long-term prognosis of patients with chronic total coronary occlusions (CTO) stratified for remaining CTOs after percutaneous coronary intervention (PCI).

Design: The study cohort consisted of patients with coronary artery disease who underwent CTO PCI in a high volume tertiary center from 2009 to 2019 and were registered in Danish high-quality registers. Patients with successful PCI of all CTOs were compared to patients with ≥1 remaining CTO post-procedural.

Cost-Effectiveness in Patients Undergoing Revascularization of Chronic Total Occluded Coronary Arteries-A Cohort Study.

Background: Revascularization of patients with chronic total occluded coronary arteries (CTO) is recommended if they have symptoms despite medical treatment. The cost-effectiveness of treatment with percutaneous coronary intervention (PCI) was investigated in this cohort study.

Materials And Methods: The study was designed as a cohort study enrolling all patients undergoing PCI for a CTO in the Central Region of Denmark and recorded in the EUROCTO database.
