Key result
Microwave ablation for atrial fibrillation during concomitant surgery yielded 62-87% sinus rhythm restoration at 6-12 months but delivered significantly inferior rates compared to RF ablation.

Caution against microwave ablation for AF in concomitant surgery; confirms inferior sinus rhythm rates versus RF ablation.
Systematic Review
Does microwave ablation improve sinus rhythm restoration in patients with atrial fibrillation undergoing concomitant cardiac surgery?
Microwave ablation is not currently recommended for the treatment of atrial fibrillation during concomitant cardiac surgery due to limited evidence and inferior outcomes compared to radiofrequency ablation.
Macdonald et al. (2012) conducted a systematic review in Atrial fibrillation. Microwave ablation vs. Radiofrequency ablation was evaluated on Sinus rhythm restoration. Microwave ablation for atrial fibrillation during concomitant surgery yielded 62-87% sinus rhythm restoration at 6-12 months but delivered significantly inferior rates compared to RF ablation.
