New heart mapping could make ablation more precise for lethal rhythm disorder
NCT ID NCT07573579
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new technique called Dynamic Voltage Mapping (DVM) to better identify scar tissue in the heart that causes ventricular tachycardia (VT), a life-threatening heart rhythm. The approach uses catheters to create a personalized electrical map, aiming to guide ablation more accurately. Researchers will enroll 40 adults with VT who already have an implantable defibrillator, comparing DVM-guided ablation to standard care.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Dynamic Voltage Mapping (a procedure using catheters to create a personalized electrical map of the heart)
What this could lead to
If successful, this mapping technique could help doctors more precisely destroy the heart tissue causing dangerous rhythms, potentially reducing the chance of VT returning after ablation.
What could go wrong
This is a small, early feasibility study with only 40 participants, so results may not apply to everyone. The technique may not prove better than standard care, and there are always risks with catheter procedures like bleeding or heart damage.
