DCB Angioplasty for Coronary Lesions: an OCT Analysis

All patients were treated with a loading dose of clopidogrel 300 or 600 mg before the procedure followed by maintenance clopidogrel 75 mg daily for 6 months. 100 U/ kg of unfractionated heparin was injected intravenously to maintain an activated clotting time ≥ 250 s during the procedure. For DCB treatment, the patient underwent predilation with an optimal-sized balloon (non-compliant balloon or cutting balloon) based on angiography (balloon-to-vessel ratio of 1.0), with the standard balloon shorter than the intended DCB size. The DCB was sized at 1:1 balloon-to-vessel ratio, delivered rapidly (median of 15 s) and inflated at nominal pressure for 60 s.
