Researchers are evaluating the safety, effectiveness, and clinical outcomes of percutaneous coronary intervention PCI for chronic total occlusions CTO in patients treated in routine clinical practice in Poland. The study seeks to understand procedural success rates, complications, and how different PCI strategies, intravascular imaging, mechanical support, and artificial intelligence analysis impact patient outcomes and quality of life. It also focuses on outcomes in various patient subgroups, including those with complex medical histories. This observational study enrolls patients undergoing CTO PCI as part of their standard care in a national, multicenter registry. Clinical, procedural, and follow-up data are collected prospectively to assess real-world outcomes. The study compares PCI performed with and without intravascular imaging and evaluates different treatment strategies such as drug-coated balloons, drug-eluting stents, and hybrid approaches. It also monitors the use of mechanical circulatory support and applies AI-based analysis of baseline electrocardiograms for outcome prediction. Participants will be followed to measure technical success of the procedure and monitor procedural details such as procedure time, fluoroscopy time, radiation dose, contrast volume, and procedural complications within one day. Additional outcomes include target lesion failure during hospital stay and up to one year, as well as mortality at one year. The study collects information on post-procedure cardiac injury markers and quality-of-life improvements, with data gathered throughout routine clinical care over the follow-up period.
