Local paclitaxel induces late lumen enlargement in coronary arteries after balloon angioplasty

Background This study investigated p aclitaxel-induced luminal changes following drug-coated balloon (DCB) angioplasty to treat coronary de novo lesions without additional stenting. DCB-mediated local drug delivery reduces late lumen loss in de novo coronary artery lesions. We performed a retrospective clinical assessment based on a pre-specified quantitative coronary angiography (QCA) protocol.
