Early Procedural and Health Status Outcomes After Chronic Total Occlusion Angioplasty: A Report From the OPEN-CTO Registry (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion Hybrid Procedures).

Objectives: This study sought to accurately describe the success rate, risks, and patient-reported benefits of contemporary chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Background: In light of the evolving techniques to successfully revascularize CTO lesions, there remains a compelling need to more accurately quantify the success rates, risks, and benefits of these complex procedures.

Methods: Using a uniquely comprehensive, core-lab adjudicated, single-arm, multicenter registry of 1,000 consecutive patients undergoing CTO PCI by the hybrid approach, we evaluated the technical success rates, complication rates, and raw and adjusted health status benefits at 1 month among successfully as compared to unsuccessfully treated patients.

The Outcomes, Patient Health Status, and Efficiency IN Chronic Total Occlusion Hybrid Procedures registry: rationale and design.

Background: Patients with chronic total occlusions of a coronary artery represent a complex, yet common, clinical conundrum among patients with ischemic heart disease. Chronic total occlusion angioplasty is increasingly being used as a treatment for these complex lesions. There is a compelling need to better quantify the safety, efficacy, benefits, and costs of the procedure.
