The optimal antithrombotic treatment in patients receiving oral anticoagulation undergoing percutaneous coronary intervention (PCI) has been a field of intensive research. Although triple antithrombotic therapy had been, until lately, the strategy of choice, recent evidence points to the superiority of dual antithrombotic therapy regarding bleeding prevention, without significantly compromising efficacy. In the further challenging scenario of complex PCI, associated with a higher ischemic risk, the efficacy of an aspirin-free strategy, adopted shortly after the index event is under question, rendering decision-making a fairly difficult scenario for clinicians. Since patients with an indication for oral anticoagulation undergoing complex PCI are underrepresented in randomized trials, there are scarce data regarding the optimal treatment strategy in such patients. This review aims to analyze and compare different approaches regarding the type and duration of antithrombotic regimens, focusing on both safety and efficacy outcomes, as well as to discuss recent guidelines’ suggestions regarding the therapeutic approach in patients receiving oral anticoagulation undergoing PCI procedures of increased complexity.
