Read our Atrial fibrillation research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
The RADAR trial tested a new computational mapping algorithm — a computer tool designed to help doctors identify and map the specific problem areas driving atrial fibrillation (persistent irregular heartbeat). Researchers created detailed 3D maps of participants' hearts during ablation procedures and studied whether the algorithm could accurately pinpoint the faulty electrical patterns that doctors should treat.
Many people with persistent irregular heartbeats don't improve with standard treatments. This trial was designed to see whether a more precise computer-guided approach could help doctors find and treat the exact sources of the irregular rhythm, potentially improving success rates.
Participants received a standard catheter ablation procedure for irregular heartbeat, during which doctors also used the new computational mapping algorithm to identify problem areas in the heart. The algorithm created detailed 3D maps of the heart's electrical activity and helped guide the doctors' treatment decisions. Participants would have completed the procedure and post-operative follow-up visits as required by the study.
