Clinical Implications

The results of our study indicate that patients with an AF/AT-free interval of at least 12 months after AF ablation have a low risk of stroke/TIA and justify further research on the safety of discontinuing OAC after successful AF ablation. Prospective, randomized studies, like the upcoming OCEAN trial (https://clinicaltrials.gov/ct2/show/NCT02168829), that will be including a similar patient population, will be needed to determine whether OAC can be safely stopped postablation or whether the risk of stroke remains high enough to justify long-term OAC continuation.
