Abstract
BACKGROUND: Current European Society of Cardiology Guidelines recommend concomitant atrial fibrillation (AF) ablation for all symptomatic patients undergoing other cardiac surgeries, but the safety and potential benefits of concomitant atrial fibrillation (AF) ablation at the time of double valve replacement (DVR: aortic and mitral valve replacement) remains unexamined.
MATERIALS AND METHODS: We conducted a retrospective review of 238 patients with AF who underwent DVR with or without concomitant surgical ablation (Ablation group, n=113; Non-ablation group, n=125) at a single institute from April 2006 to September 2011.
RESULTS: There were no significant group differences in early postoperative mortality and morbidity, late survival, and freedom from major cardiac and cerebrovascular events (MACCEs). However, the Ablation group exhibited higher rates of sinus rhythm restoration at discharge (86.7% vs. 5.6%, P<0.01) and at last follow-up (71.2% vs. 8.5%, P<0.01). Follow-up echocardiography demonstrated smaller left atrial dimension and higher ejection fraction in the Ablation group (both P <0.01).
CONCLUSION: Concomitant surgical ablation for AF did not increase perioperative mortality or morbidity in patients undergoing DVR, but significantly increased sinus rhythm restoration, improved heart function, and decreased oral anticoagulation requirements.
