Key result
Radiofrequency catheter ablation of right septal or posteroseptal accessory pathways in WPW syndrome improved left ventricular ejection fraction from 50% to 56% (P=0.0005).
Why the study?
Does radiofrequency catheter ablation improve left ventricular function in patients with Wolff-Parkinson-White syndrome with right septal or posteroseptal accessory pathways?
Cohort (n=34)
Does radiofrequency catheter ablation improve left ventricular function in patients with Wolff-Parkinson-White syndrome with right septal or posteroseptal accessory pathways?
Absolute Event Rate: 56% vs 50%
p-value: p=0.0005
Radiofrequency catheter ablation of right septal or posteroseptal accessory pathways in WPW syndrome improves LV dyssynchrony and global LV function.
No takes yet. Share an insight, caveat, or question.
May support ablation consideration for LVEF in WPW with right septal pathways; leaves open randomized confirmation.
Tomaske et al. (2008) conducted a cohort in Wolff-Parkinson-White syndrome with right septal or posteroseptal accessory pathways (n=34). Radiofrequency catheter ablation (RFA) vs. Baseline (prior to RFA) was evaluated on Left ventricular ejection fraction (p=0.0005). Radiofrequency catheter ablation of right septal or posteroseptal accessory pathways in WPW syndrome improved left ventricular ejection fraction from 50% to 56% (P=0.0005).
