Predictors and Long-term Incidence of In-stent Restenosis After Chronic Total Occlusion Percutaneous Coronary Intervention

The goal of this clinical trial is to describe the long-term (≥ 3 years) patency of coronary artery stents following chronic total occlusion percutaneous coronary intervention (CTO PCI). The main questions it aims to answer are: * What is the incidence of in-stent restenosis after CTO PCI? * What are patient-, lesion-, and procedure-related factors associated with an increased risk of in-stent restenosis after CTO PCI?
