Why the study?
Does surgical AF ablation during cardiac surgery improve freedom from AF, mortality, and stroke in patients with atrial fibrillation?
Does surgical AF ablation during cardiac surgery improve freedom from AF, mortality, and stroke in patients with atrial fibrillation?
Surgical AF ablation during cardiac surgery improves freedom from AF but lacks significant mortality or stroke benefits, with biatrial lesions carrying a higher pacemaker risk than left-sided ones.
Surgical AF ablation improves AF freedom without reducing mortality or stroke; confirms limited hard-outcome benefit and cautions against routine biatrial lesions due to pacemaker risk.
Surgical AF ablation during cardiac surgery improves freedom from AF. However, impact on patient-important outcomes including mortality and stroke has not shown statistical significance in current RCT evidence. Biatrial compared with left-sided lesion sets showed no difference in mortality or stroke but were associated with significantly increased freedom from AF and risk for pacemaker requirement.
