Key result
Left atrial cryoablation during mitral valve surgery is linked to ~67% stable sinus rhythm long-term.
Why the study?
Recent surgical trends for AF have shifted toward safer, more effective energy sources and simplified lesion sets.
Does isolated left atrial cryoablation combined with conventional mitral valve surgery improve long-term freedom from atrial fibrillation in patients with AF and mitral valve disease?

Does isolated left atrial cryoablation combined with conventional mitral valve surgery improve long-term freedom from atrial fibrillation in patients with AF and mitral valve disease?
Isolated left atrial cryoablation during conventional mitral valve surgery provides good long-term freedom from atrial fibrillation, though preoperative left atrial dilation and pulmonary hypertension increase the risk of recurrence.
Gatti et al. (2020) conducted a cohort in paroxysmal/persistent atrial fibrillation and mitral valve disease (n=118). Isolated left atrial cryoablation was evaluated on Stable sinus rhythm at follow-up. Isolated left atrial cryoablation during conventional mitral valve surgery resulted in 66.7% of patients in stable sinus rhythm at a median 6.6 years follow-up.
