Clinical outcomes of drug-coated balloon in coronary lesions: a real-world, all-comers study

Backgrounds Although drug-eluting stents are the most common interventional devices for patients with coronary disease, drug-coated balloons (DCBs) represent a novel therapeutic alternative in certain scenarios. This prospective, observational all-comers study explored the clinical outcomes of DCB use in patients with coronary lesions. Methods and results All patients treated with DCBs were enrolled in this study, including patients with in-stent restenosis (ISR) or de novo lesions. The primary outcome was the target lesion revascularization (TLR) rate at one year. We enrolled 2306 patients with 2660 lesions and performed DCB angioplasty in 399 patients (17.3%) with ISR and 1907 patients (82.7%) with de novo lesions. During follow-up (366 ± 46 days), the TLR rate was lower in the de novo lesion group (1.31%) compared to the ISR group (7.02%) [odds ratio (OR) 0.176, 95% confidence interval (CI) 0.101–0.305, p
