Left atrial catheter ablation has become an established therapy to abolish symptomatic paroxysmal and persistent atrial fibrillation. Most patients undergoing (several) catheter ablation procedures have sufficient symptom relief. In addition, restoring sinus rhythm may help to prevent AF-related complications on the long-term. This review summarizes the current knowledge regarding ablation-related neurological complications. Neurological complications occur in 0.4 to 1.2% of all patients undergoing ablation and are predominantly caused by cerebral ischemia. Non-ischemic neurological complications are rare and are generally caused by phrenic nerve paralysis. In addition, neurological complications frequently occur after atrio-oesophageal fistula, a rather seldom complication of left atrial catheter ablation. Moreover, MRI-detected brain lesions without corresponding neurological symptoms can be common after catheter ablation procedures, and may depend on the ablation technology employed. However, the clinical relevance of these ischemic brain lesions is not totally understood so far.
