New ablation technique aims to zap heart flutter with less radiation and greater precision

NCT ID NCT04678258

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This trial tests a new way to treat typical atrial flutter, a heart rhythm problem. Instead of the standard linear ablation, doctors use a special catheter with tiny sensors to map and target only the high-voltage areas causing the flutter. The goal is to see if this approach is as effective as the standard method while using less radiation and fewer burns. About 100 adults with atrial flutter will be randomly assigned to one of the two techniques, and the results will be checked during the procedure and afterward.

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 (IntellaMiFi micro-sensor technology)

What this could lead to

If successful, this approach could make atrial flutter ablation faster, more precise, and radiation-free, potentially improving patient outcomes and reducing procedure time.

What could go wrong

This is a relatively small, early-stage trial comparing two techniques, so results may not apply broadly. The new method might not be as effective in the long term or could carry a risk of hidden conduction gaps.
