Costs of surgical ablation of atrial fibrillation in Ontario, Canada from 2006 to 2017

International guidelines currently recommend concomitant surgical ablation of atrial fibrillation (AF) in patients with AF undergoing cardiac surgery. However, a systematic review and meta‐analysis of 23 randomized controlled trials (RCTs) showed no significant difference in mortality or stroke in patients who underwent surgical AF ablation compared with those who did not (moderate‐quality evidence).
