Key result
Radiofrequency ablation during mitral valve surgery achieved sinus rhythm recovery in 78.8% of patients at 29.5 months, which was associated with significantly lower hospital readmission (97.4% vs 60.6%, p=0.0003).
Why the study?
Does successful radiofrequency ablation during mitral valve surgery improve atrio-ventricular remodelling and clinical outcomes in patients with atrial fibrillation?
Cohort (n=52)
Does successful radiofrequency ablation during mitral valve surgery improve atrio-ventricular remodelling and clinical outcomes in patients with atrial fibrillation?
Successful radiofrequency ablation during mitral valve surgery restores sinus rhythm in a majority of patients, leading to significant atrio-ventricular reverse remodeling and reduced hospital readmissions.
No takes yet. Share an insight, caveat, or question.
May support ablation to lower readmissions in mitral surgery with AF; leaves open causal remodeling benefits pending RCTs.
Onorati et al. (2007) conducted a cohort in Atrial fibrillation in patients undergoing mitral valve surgery (n=52). Radiofrequency atrial fibrillation ablation during mitral valve surgery was evaluated on Sinus rhythm recovery. Radiofrequency ablation during mitral valve surgery achieved sinus rhythm recovery in 78.8% of patients at 29.5 months, which was associated with significantly lower hospital readmission (97.4% vs 60.6%, p=0.0003).
