Bottom line: “Observational data suggest that successfully ablated atrial fibrillation patients have very low rates of stroke (<0.7% per year) despite cessation of OAC [oral anticoagulation] after ablation. High-quality, randomized clinical trials are needed to address whether long-term OAC use may be obviated in patients who have had successful atrial fibrillation ablation.” “CHADS2 and CHA2DS2-VASc scores could be used to identify patients at the risk of TE events after ablations who should continue OACs despite the status of recurrence” of thromboembolic (TE) events.
