Key result
Endocardial cryoablation and epicardial RF ablation during endoscopic mitral valve repair resulted in statistically equivalent 6-month AF-free rates (74% vs 82%).
Why the study?
Does left-sided epicardial RF ablation compared to endocardial cryoablation improve AF-free rates in patients with atrial fibrillation undergoing endoscopic mitral valve repair?
Cohort (n=112)
Does left-sided epicardial RF ablation compared to endocardial cryoablation improve AF-free rates in patients with atrial fibrillation undergoing endoscopic mitral valve repair?
Absolute Event Rate: 74% vs 82%
Both endocardial cryoablation and epicardial RF ablation are effective concomitant treatments for atrial fibrillation during endoscopic mitral valve repair, though cryoablation may be associated with a higher need for pacemaker implantation.
No takes yet. Share an insight, caveat, or question.
Equivalent 6-month AF-free rates with either ablation during endoscopic MV repair; leaves open randomized confirmation of choice and pacemaker risk.
Krakor et al. (2011) conducted a cohort in Atrial fibrillation (n=112). Endocardial cryoablation vs. Epicardial RF ablation was evaluated on AF-free rate at 6 months. Endocardial cryoablation and epicardial RF ablation during endoscopic mitral valve repair resulted in statistically equivalent 6-month AF-free rates (74% vs 82%).
