New mapping technique may improve heart rhythm procedure
NCT ID NCT03915691
First seen Jun 24, 2026 · Last updated Jun 24, 2026
Summary
This study tests two ways to do a catheter ablation for a type of fast heartbeat called atrial tachycardia that comes from heart scar tissue. One method uses a new mapping system (Ripple Mapping) to guide the ablation, while the other uses the standard approach. The goal is to see which method better prevents the arrhythmia from coming back within a year. About 200 adults who need this procedure are taking part.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Catheter ablation (Ripple Mapping guided or conventional mapping guided)
What this could lead to
If successful, this could identify a more effective ablation technique to reduce the return of atrial tachycardia after the procedure.
What could go wrong
This is a mid-stage study with no phase designation, and the outcome depends on long-term follow-up. The procedure itself carries standard risks like bleeding or heart damage.
