The approach to patients with an indication for oral anticoagulation (OAC) for atrial fibrillation (AF) who undergo coronary stenting and thus need dual antiplatelet therapy has long been debated. Dual antiplatelet therapy accompanied by OAC (so called "triple therapy") carries a high bleeding risk and thus should either be avoided or used for a limited period. The lack of relevant prospective randomised trial data have largely been overcome by the recently published PIONEER AF-PCI trial, the results of which will be summarized in this article.
