Heart ablation gets a Radiation-Free upgrade with internal ultrasound
NCT ID NCT07201506
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using a tiny ultrasound camera inside the heart during ablation can reduce or replace X-rays. Ablation uses catheters to fix abnormal heart rhythms, and X-rays are normally used to guide them. Half of the 70 participants will get the ultrasound-guided procedure, the other half standard care. The goal is to see if this new approach lowers radiation exposure while keeping the treatment safe and effective.
