Does OAC discontinuation increase the risk of cardioembolism in patients after catheter ablation for atrial fibrillation?
Patients after catheter ablation for atrial fibrillation
Oral anticoagulation (OAC) discontinuation
Continuing OAC
Risk of stroke or cardioembolismhard clinical
Continuing OAC for at least 3 months in all patients and indefinitely in high-risk patients after AF ablation is the safest strategy to prevent cardioembolism.
The overall risk of stroke in postablation patients is low; however, OAC discontinuation after ablation is common and is associated with increased risk of cardioembolism for all patients within the first 3 months and for high-risk patients in the long term. Continuing OAC for at least 3 months in all patients and indefinitely in high-risk patients appears to be the safest strategy.
