Drug-Coated Balloon vs. Drug-Eluting Stent for Clinical Outcomes in Patients With Large Coronary Artery Disease

Although several reports suggested that DCB application was safe for larger coronary artery lesions and showed good long-term outcomes, there is limited randomised controlled trial (RCT) data on the safety and efficacy of DCB in large coronary artery disease. Therefore, the study aims to demonstrate the non-inferiority of the drug-coated balloon (DCB) treatment against current-generation drug-eluting stenting (DES) in patients with de novo lesions in large coronary artery disease (reference vessel diameter ≥3.0 mm by visual estimation). The hypothesis of the study is the clinical outcomes of patients treated with DCB are non-inferior to those treated with current-generation DES.
