Abstract

Objectives: We sought to answer whether one-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 one-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 was conducted from January 1st, 2012 to March 31st, 2017 from a high-volume, tertiary PCI cente. All patients who received a one-month duration of DAPT after elective DCB angioplasty were included. We identified a primary composite outcome of cardiac death, myocardial infarction and target lesion revascularisation at 6-months. Results: This included 303 patients (78.5% male) with a mean age of 67±12.5. This incorporated 86.1% de novo lesions and 56.5% non-small (3mm 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%) non-target vessel MIs and one (0.3%) non-cardiac 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 non-small coronary arteries treated with DCB-only angioplasty. A one-month duration of DAPT appears a safe and attractive option.
