Drug-Coated Coronary Balloons in Different Clinical Scenarios

The study population will consist of adult patients (≥18 years) with coronary artery disease who undergo percutaneous coronary intervention (PCI) in routine clinical practice in participating centers and are treated with a drug-coated balloon (DCB) for at least one target coronary lesion. The registry will include patients across a broad spectrum of clinical presentations, including stable coronary artery disease and acute coronary syndromes, and will encompass a wide range of lesion subsets such as de novo lesions, in-stent restenosis, bifurcation lesions, small and large vessels, and chronic total occlusions. Both prospectively and retrospectively enrolled patients will be included, reflecting real-world practice without additional diagnostic or therapeutic interventions beyond standard of care. The population will therefore represent an unselected, all-comer cohort treated with contemporary DCB-based strategies, allowing comprehensive evaluation of clinical and procedural outcomes.
