Early cerebral thromboembolic complications after radiofrequency catheter ablation of atrial fibrillation: incidence, characteristics, and risk factors.

Background: Thromboembolic complications remain one of the most severe adverse events associated with catheter ablation of atrial fibrillation (AF), but data on such events are limited.

Objective: The purpose of this study was to evaluate the incidence, characteristics, and risk factors of thromboembolic complications after AF ablation.

Methods: Cerebral thromboembolic complications occurring within 1 month of 3360 consecutive AF radiofrequency catheter ablations were assessed.

Atrial arrhythmias following surgical AF ablation: electrophysiological findings, ablation strategies, and clinical outcome.

Background: Intraoperative atrial fibrillation (AF) ablation during cardiac surgery is a well-established treatment. However, tachycardia mechanisms, ablation strategies, and long-term follow-up of atrial arrhythmias (AA) following intraoperative AF ablation (AFA) have not been previously studied in a large cohort of patients.

Objective: Eighty-two patients (48 male, median age of 65 years) with symptomatic recurrence of AA following intraoperative AFA underwent radiofrequency catheter ablation.
