Atrial Fibrillation study: CT
Official title 320-detector Computed Tomography to Assess Myocardial Extracellular Volume Fraction in Patients With Atrial Fibrillation Before AF Ablation.
ClinicalTrials.gov ID: NCT06308094
What this study is testing
- What it's testing
- The study wants to see if the amount of scar tissue measured by CT can predict AF coming back, hospital stays, or heart function after ablation.
- Who it's for
- Adults who have atrial fibrillation and are planning to undergo catheter ablation.
- What's involved
- You will have a cardiac CT scan that measures extracellular volume (a sign of scar tissue) and will follow the usual care for your ablation.
- Time commitment
- A single CT scan visit before the ablation procedure.

You may be able to join if
- Patients must be at least 21 years old at the time of enrollment.
- Patients must be able to give informed consent.
- Patients with symptomatic paroxysmal/persistent atrial fibrillation (AF).
- Eligible patients must be determined to be suitable candidates for ablation to treat AF by their cardiologist and/or electrophysiologists regardless...
