Ultrasound-guided heart procedure to treat a fast rhythm
Part of Heart & circulation clinical trials.
This trial tests a way to stop a specific fast heart rhythm (AVNRT) using a freezing treatment guided by an ultrasound camera inside the heart. It may help people whose heart rhythm episodes come from a “slow pathway” wiring circuit.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your ECG or Holter monitor shows a regular fast heartbeat with narrow QRS complexes
- Doctors can show, during the procedure, that you have AVNRT (an AV node re-entrant tachycardia) using pacing maneuvers
- You are expected to live at least 12 months (not a terminal or very severe condition)
- Your groin vein access is possible (no deep vein clot blocking the femoral vein)
- You do not have clots inside the heart
- Your pelvic/large vein anatomy is suitable for catheter access (no major vessel shape problems)

This trial tests a freezing catheter procedure to treat dangerous, recurring abnormal heart rhythms (ventricular tachycardia) in patients whose hearts are weakened and whose current medications haven't worked. The procedure aims to scar the tissue causing the arrhythmia so your heart beats normally again.
This trial compares two procedures to treat very slow heart rates without needing a pacemaker. One uses freezing (cryoablation) and the other uses radiofrequency energy to target nerves that control heart rate.
This study tests a new catheter-based treatment for people with certain types of very fast or extra heartbeats that come from the lower chambers of the heart. The catheter uses a special energy to stop the abnormal beats and might help if you have had symptoms despite other treatments.
This trial tests a new way to treat a fast heart rhythm called PSVT using a procedure that avoids X-ray radiation. It aims to see if this approach is safer and works well for patients who need this treatment.
This study is for people who are already scheduled for a heart procedure to treat ventricular tachycardia. It will use a special freezing (cryoablation) system to see how well it works in everyday practice.
This trial tests a new way to treat rapid heartbeats from the lower chambers (ventricles) using a special catheter that delivers short electrical pulses to stop the abnormal signals. It may help people with extra beats (PVCs) or a fast heart rhythm (ventricular tachycardia) that needs treatment.
