Cerebral Infarction After Radiofrequency Catheter Ablation in Patients With Paroxysmal Atrial Fibrillation

ABSTRACT

Radiofrequency catheter ablation (RFCA) is a useful treatment for drug-refractory atrial fibrillation. RFCA can cause cerebral infarction that remains the neurologic deficit if prompt managements are delayed. We report on 3 patients who developed cerebral infarctions immediately after RFCA. Periprocedural anticoagulation such as warfarin should be continued for patients, even if they are at low risk for cerebral infarction.
