New heart catheter zaps away irregular rhythms without heat or cold
NCT ID NCT06056557
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tested a new catheter system that uses pulsed field energy to treat atrial fibrillation and related arrhythmias. In 141 patients, doctors used the VARIPULSE catheter with a 3D mapping system to destroy the heart tissue causing the irregular rhythm. The goal was to see if the procedure is safe and effective at stopping the abnormal signals.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
VARIPULSE catheter ablation device
What this could lead to
If successful, this could offer a safer and more precise way to treat atrial fibrillation using pulsed field energy instead of heat or cold.
What could go wrong
This is a small, completed study without a control group, so results may not apply to all patients. The procedure still carries risks like any heart ablation.
