Evaluating factors affecting outcomes after catheter ablation for atrial fibrillation

The Evaluation for Prognostic Factors After Catheter Ablation of Atrial Fibrillation: Cohort Study

Observational Yonsei University · NCT02138695

This study looks at how different factors like age and sex affect whether atrial fibrillation comes back after patients have a catheter ablation treatment.

What this trial studies

This observational study aims to identify clinical factors associated with the recurrence of atrial fibrillation after catheter ablation. It will explore various characteristics such as age, sex, and imaging results to develop a predictive model for clinical outcomes. The study seeks to enhance understanding of how different variables influence the efficacy of catheter ablation in patients with symptomatic, drug-refractory atrial fibrillation.

Who should consider this trial

Good fit: Ideal candidates are patients with symptomatic, drug-refractory atrial fibrillation who are undergoing catheter ablation.

Not a fit: Patients with permanent atrial fibrillation, significant valvular disease, or those under 19 years old may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved patient selection and outcomes for those undergoing catheter ablation for atrial fibrillation.

How similar studies have performed: Previous studies have shown that catheter ablation can be more effective than drug therapy, but this specific multifactorial approach is relatively novel.
