Objective: To assess the safety and efficacy of paclitaxel- vs. sirolimus-coated drug-eluting balloon over 12 months in patients undergoing coronary angioplasty for in-stent restenosis or small-vessel stenosis. Secondary

Objectives: To compare the efficacy (freedom from target vessel failure) of both balloons at 12 months. To evaluate the safety of paclitaxel- vs. sirolimus-coated balloon in coronary revascularization at 12 months. Study

Design: Study Type: Prospective, single-center, analytical cohort study. Population: Patients undergoing angioplasty with paclitaxel- or sirolimus-coated drug-eluting balloons according to standard clinical practice. Inclusion Criteria: Patients with De novo lesion and in stent reestenosis. Study Period: From September 2021 to September 2026 or until the required sample size is achieved. Study Importance: This study will provide comparative evidence on the use of paclitaxel- and sirolimus-coated DCBs in coronary revascularization. The findings may contribute to future clinical recommendations for the optimal use of DCBs in patients with coronary artery disease.
