New balloon catheter zaps heart rhythm problem in early trial
NCT ID NCT07294742
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tests a new balloon-shaped catheter that uses pulsed electric fields to treat persistent atrial fibrillation, a type of irregular heartbeat. Thirty-four adults aged 18 to 75 with the condition will receive the procedure. Researchers will check safety within 7 days and see how well the catheter creates lasting scar tissue to block faulty signals.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Balloon-shaped large-focal pulsed field ablation catheter
What this could lead to
If successful, this could provide a safer and more effective way to treat persistent atrial fibrillation, potentially reducing the need for repeat procedures.
What could go wrong
This is a very early, small study with only 34 participants, so results may not apply to everyone. The procedure carries risks like heart tissue damage or nerve injury, and long-term benefits are not yet proven.
