Using virtual drug testing to improve treatment for recurrent atrial fibrillation after catheter ablation

Clinical Usefulness of Virtual Antiarrhythmic Drug Test in Patients With Recurred AF After Catheter Ablation(CUVIA-AF3)

Not applicable Interventional Yonsei University · NCT04223310

This study is testing if a new virtual system for choosing heart medications can help people with recurring atrial fibrillation feel better after their catheter procedure compared to the usual method.

What this trial studies

This study aims to evaluate the effectiveness and safety of a virtual antiarrhythmic drug (AAD) testing system for patients who experience recurrent atrial fibrillation (AF) after catheter ablation. It involves a prospective randomized design where participants will be assigned to either a virtual AAD test group or an empirical AAD group. The study will monitor patients' heart rhythms using Holter monitoring and ECGs at various intervals to assess the efficacy of the AADs selected through computer modeling versus traditional methods. The goal is to determine if personalized AAD selection can lead to better outcomes in managing recurrent AF.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 20 to 80 who have experienced recurrent atrial fibrillation after catheter ablation and are suitable for AAD therapy.

Not a fit: Patients with permanent atrial fibrillation or significant structural heart disease are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more effective treatment options for patients with recurrent atrial fibrillation, potentially reducing recurrence rates and improving quality of life.

How similar studies have performed: While the use of virtual modeling for drug efficacy evaluation is a novel approach, similar studies have shown promise in improving treatment outcomes for various conditions.
