Evaluating heart function during exercise after ablation for atrial fibrillation
Official title: EXCLAMATORY: EXercise Cardiac Magnetic Resonance Assessment of Left Atrial Mechanics Following Ablation TO Reduce Atrial Fibrillation Burden and Correlation With Exercise CapacitY Longitudinal Study
Run by Virginia Commonwealth University · NCT06212791 · Data updated 2026-11-12
This study is testing how well the heart works during exercise in people who have had a procedure to treat their irregular heartbeat, to see if their ability to exercise improves over time.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older diagnosed with paroxysmal atrial fibrillation who are scheduled for catheter ablation.
✕Probably not a fit
Patients with persistent or permanent atrial fibrillation, significant heart conditions, or those unable to complete required assessments may not 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 observational cohort study aims to assess changes in left atrial reservoir function and overall exercise capacity in patients who have undergone catheter ablation for paroxysmal atrial fibrillation. Participants will undergo various evaluations, including self-reported questionnaires and cardiopulmonary exercise tests, to measure their heart performance during physical activity. The study will track these changes over time to better understand the impact of the ablation procedure on exercise capacity and heart function.
Why it matters
Potential benefit: If successful, this study could provide insights into improving post-ablation care and exercise recommendations for patients with atrial fibrillation.
How similar studies have gone: While similar studies have explored heart function post-ablation, this specific focus on left atrial mechanics during exercise is relatively novel.
