Insertable heart monitor to catch early atrial fibrillation after catheter ablation

Insertable Cardiac Monitor-Guided Early Intervention to Reduce Atrial Fibrillation Burden Following Catheter Ablation (ICM-REDUCE-AF Trial)

NIH-funded research University of Rochester · NIH-11176391

This trial tests whether a small implanted heart monitor that finds early, often-silent atrial fibrillation and prompts early treatment can help people with drug-resistant atrial fibrillation after catheter ablation.

What this research studies

You would have a small insertable cardiac monitor placed and be randomly assigned to either get early treatment guided by the monitor and a patient mobile app or to follow standard post-ablation care. The monitor continuously records your heart rhythm to detect subclinical atrial fibrillation you might not feel. The trial is double-blind to the subclinical monitoring data and will enroll about 120 patients at a single center. Researchers will compare how much atrial fibrillation occurs and whether early actions reduce recurrences over the follow-up period.

Who could benefit from this research

Good fit: Adults with drug-refractory paroxysmal or persistent atrial fibrillation who are scheduled for catheter ablation and are willing to have an insertable cardiac monitor implanted are the ideal candidates.

Not a fit: People who are not undergoing catheter ablation, who cannot have an implanted monitor, or who cannot attend required follow-up visits are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, this approach could reduce the amount of atrial fibrillation you experience after ablation and lower the need for repeat procedures or additional medications.

How similar studies have performed: Prior studies show catheter ablation can lower AF and insertable monitors reliably detect silent AF, but using continuous monitor-guided early intervention after ablation is a newer strategy that remains unproven.
