Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are patients with permanent or persistent atrial fibrillation and New York Heart Association (NYHA) Class II-IV heart failure symptoms.

Probably not a fit

Patients with a life expectancy of less than one year from non-cardiac causes or those requiring intensive care are unlikely to benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to evaluate a novel approach for managing atrial fibrillation (AF) in patients who have heart failure symptoms. The method involves implanting a pacemaker and performing ablation on the atrioventricular (AV) node to regulate heart rhythm effectively. By intentionally damaging the AV node, the trial seeks to prevent AF from affecting the heart's ventricles, allowing the pacemaker to maintain a stable heart rate. This approach is particularly targeted at patients who struggle with medication side effects or ineffective treatments.

Why it matters

Potential benefit: If successful, this approach could provide a permanent solution for patients with atrial fibrillation and heart failure, improving their quality of life.

How similar studies have gone: Other studies have shown promise in using similar approaches for managing atrial fibrillation, indicating potential for success in this trial.
