Key result
Radiofrequency ablation shows similar 12-month sinus rhythm maintenance to cryoablation during mitral valve surgery.
Why the study?
Does radiofrequency ablation improve maintenance of sinus rhythm compared to cryoablation in patients undergoing concomitant mitral valve surgery?
Cohort (n=96)
Does radiofrequency ablation improve maintenance of sinus rhythm compared to cryoablation in patients undergoing concomitant mitral valve surgery?
Absolute Event Rate: 88.1% vs 83.3%
In patients undergoing concomitant mitral valve surgery and AF ablation, the energy source (radiofrequency vs cryoablation) does not significantly impact sinus rhythm maintenance at 12 months, whereas patient characteristics like LA diameter and hypertension are strong predictors of recurrence.
No takes yet. Share an insight, caveat, or question.
Energy source choice did not affect sinus rhythm maintenance; leaves open demographic factors' role in ablation success.
Vural et al. (2018) conducted a cohort in Atrial fibrillation (n=96). Radiofrequency ablation vs. Cryoablation was evaluated on Maintenance of sinus rhythm at 12 months. Radiofrequency ablation and cryoablation resulted in similar rates of sinus rhythm maintenance at 12 months (88.1% vs 83.3%) during concomitant mitral valve surgery.
