AI heart maps may forecast who needs more than a standard ablation for AFib

First seen Sep 08, 2026 · Last updated Sep 10, 2026 · Updated 2 times
Summary
This study tests whether artificial intelligence software can predict if atrial fibrillation will return within a year after a standard ablation procedure. Researchers will use the Volta AF-Xplorer II software to map abnormal electrical areas in the hearts of 125 people with persistent atrial fibrillation before and after pulmonary vein isolation. The goal is to see if the location and extent of these abnormal areas, called spatiotemporal dispersion, relate to whether the arrhythmia comes back.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Volta AF-Xplorer II artificial intelligence software used during catheter ablation to map heart tissue
- What this could lead to
- If the software's maps predict who will have atrial fibrillation return after ablation, doctors could tailor procedures to reduce repeat episodes.
- What could go wrong
- This is an observational study, not a treatment test. The software's predictions may not prove reliable, and results may not apply beyond the specific ablation technique used.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patient aged 18 years or older. 2. De novo patient candidate for catheter ablation of persistent atrial fibrillation (AF episode \>7 days). 3. Continuous anticoagulation for more than 4 weeks before ablation. 4. Patient giving his signed consent form to participate in the clinical study. 5. Patient affiliated to the French social security. Exclusion Criteria: 1. Contraindication to AF/AT catheter ablation. 2. Major bleeding disorder. 3. Contraindication to anticoagulation (Heparin, Warfarin or NOAC…) or lack of anticoagulation for 4 weeks prior to the procedure. 4. Presence of a LA thrombus on transesophageal echocardiography (TEE) prior to the procedure. 5. History of blood clotting or bleeding abnormalities 6. Acute illness or active systemic infection or sepsis 7. Any cardiac surgery within the past 2 months (60 days) (includes PCI) 8. Myocardial infarction within the past 2 months (60 days) 9. Awaiting cardiac transplantation or other cardiac surgery within the next 12 months (365 days) 10. Diagnosed atrial myxoma 11. Presence of intramural thrombus, tumor or other abnormality or condition that precludes vascular access, or manipulation of the catheter 12. Documented thromboembolic event (including TIA) within the past 12 months (365 days) 13. Unstable angina within the past month 14. Significant severe pulmonary disease, (e.g. patients with restrictive pulmonary disease, constrictive or chronic obstructive pulmonary disease in GOLD stage IV) or any other disease or malfunction of the lungs or respiratory system that produces chronic symptoms (e.g. unstable or untreated sleep apnea) 15. Patient who is or could potentially be pregnant. 16. Person deprived of liberty or under guardianship. 17. Patient's refusal to participate in the study.
