Abstract

Objectives: We sought to answer whether 1-month duration of dual antiplatelet therapy (DAPT) is safe after elective drug-coated balloon only (DCB) angioplasty. Background: The duration of DAPT after elective DCB was called into question after the ESC Focused DAPT Update of 2017. Until then, a 1-month duration of DAPT was considered safe by national consensus groups (German, Italian, and Chinese) supported by data from prospective worldwide registries. The ESC Guidelines recommended a 6-month duration of DAPT based on evidence from in-stent restenosis randomized controlled trials only. Methods: Retrospective, real-world population, single-center analysis conducted from January 1, 2012 to March 31, 2017 in a high-volume, tertiary PCI center. Consecutive patients receiving 1-month duration of DAPT after elective DCB angioplasty were included. We identified a primary composite outcome of cardiac death, myocardial infarction and target lesion revascularization at 6-months. Results: A total of 303 patients (78.5% male) with mean age of 67 ± 12.5 were included. This incorporated 86.1% de novo lesions and 56.5% nonsmall (≥3 mm diameter) coronary arteries treated. There were no reported outcomes of lesion thrombosis, target vessel MI, target lesion revascularization or cardiac death at 6-months. There were two (0.6%) nontarget vessel MIs and one (0.3%) noncardiac death. Conclusion: One-month duration of DAPT appears safe after elective DCB-only angioplasty, highlighting this strategy for patients at high-risk of bleeding. These results also show favorable clinical outcomes for de novo coronary artery disease and nonsmall coronary arteries treated with DCB-only angioplasty. A 1-month duration of DAPT appears a safe and attractive option.
