NCT07330622

Brief Summary

The goal of this observational study is to evaluate the safety, efficacy, and clinical outcomes of percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) in patients treated in contemporary clinical practice in Poland. The main questions it aims to answer are:

  • What are the rates of procedural success and periprocedural complications of CTO PCI in routine clinical practice?
  • How do CTO PCI strategies and techniques, intravascular imaging, different treatment strategies, and mechanical circulatory support affect clinical outcomes?
  • How do clinical outcomes differ among different patient subgroups?
  • Can artificial intelligence-based analysis predict clinical and quality-of-life outcomes after CTO PCI? Patients undergoing CTO PCI as part of their standard medical care will be prospectively enrolled in a national, multicenter registry, with clinical, procedural, and follow-up data collected to evaluate real-world outcomes.
