The antithrombotic management of patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) poses numerous challenges. Triple antithrombotic therapy (TAT), which combines dual antiplatelet therapy (DAPT) with oral anticoagulation (OAC), provides anti-ischemic protection but increases the risk of bleeding. Therefore, TAT is generally limited to a short phase (1 week) after PCI, followed by aspirin withdrawal and continuation of 6-12 months of dual antithrombotic therapy (DAT), comprising OAC plus clopidogrel, followed by OAC alone. This pharmacological approach has been shown to mitigate bleeding risk while preserving adequate anti-ischemic efficacy. However, the decision-making process remains complex in elderly patients and those with co-morbidities, significantly influencing ischemic and bleeding risk. In this review, we discuss the available evidence in this area from randomized clinical trials and meta-analyses for post-procedural antithrombotic therapies in patients with non-valvular AF undergoing PCI.
