Catheter ablation of atrial arrhythmias in cardiac sarcoidosis.
We previously reported on the incidence and clinical implications of supraventricular arrhythmia in patients with cardiac sarcoidosis (CS). The role of catheter ablation for the management of atrial arrhythmia (AA) in this patient population is unknown. ⋯ Our study suggests that AA in CS is frequently left atrial in origin. Catheter ablation appears to be effective and safe for the maintenance of sinus rhythm in patients with CS.

Long-term outcome of catheter ablation in atrial fibrillation patients with coexistent metabolic syndrome and obstructive sleep apnea: impact of repeat procedures versus lifestyle changes.
Metabolic syndrome (MS) and obstructive sleep apnea (OSA) are well-known independent risk factors for atrial fibrillation (AF) recurrence. This study evaluated ablation outcome in AF patients with coexistent MS and OSA and influence of lifestyle modifications (LSM) on arrhythmia recurrence. ⋯ MS and OSA have additive negative effect on arrhythmia recurrence following single procedure. Repeat ablation or compliant LSM increase freedom from recurrent AF.
