Study Details

The TURK CTO Registry is a prospective, multicenter, observational registry designed to evaluate the contemporary management and outcomes of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) in Türkiye. The registry will include consecutive adult patients undergoing CTO PCI at participating centers. Detailed data on patient characteristics, cardiovascular risk factors, lesion and procedural characteristics, CTO crossing strategies, guidewires and devices, procedural techniques, radiation exposure, contrast use, procedural success, and in-hospital complications will be collected using a standardized electronic data collection system. The primary objective of the registry is to characterize contemporary CTO PCI practice in Türkiye and to evaluate procedural success and safety. Secondary objectives include identifying clinical, angiographic, and procedural factors associated with technical and procedural success, complications, resource utilization, and patient outcomes. The registry is expected to provide real-world, multicenter data on CTO PCI practice and to help identify factors associated with successful and safe CTO revascularization in Türkiye. No treatment or procedural strategy will be assigned by the study protocol; all clinical and procedural decisions will be made by the treating physicians according to routine clinical practice.

70,000 participants (estimated)

Arms

  • Arm: CTO PCI Cohort
    Adult patients (≥18 years) undergoing attempted percutaneous coronary intervention (PCI) for at least one coronary chronic total occlusion (CTO) at participating centers in Türkiye will be prospectively enrolled. The cohort will include both successful and unsuccessful CTO PCI procedures, as well as repeat CTO PCI attempts. If a patient undergoes more than one CTO PCI attempt or treatment of more than one CTO lesion during the study period, each eligible procedure will be recorded as a separate procedural episode and linked to the same patient using a unique study identifier. No specific CTO PCI strategy, technique, device, or treatment will be assigned by the study protocol. All procedural and clinical decisions will be made by the treating physicians according to routine clinical practice.

Primary Outcome Measure

Technical Success of CTO PCI [ Time Frame: At the end of the index CTO PCI procedure ]
