Testing heart rhythm mapping in repaired tetralogy of Fallot
Part of Genetic & congenital, Heart & circulation clinical trials.
This study validates a new method to locate abnormal heart rhythms using ECG (a simple heart recording) in adults who had tetralogy of Fallot surgery as children. Researchers will compare the new mapping technique during a scheduled heart procedure to improve how doctors find and treat dangerous rhythms in the future.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are at least 18 years old
- You had surgery to repair tetralogy of Fallot (a congenital heart defect) and now have pulmonary stenosis (narrowing of the valve)
- You already have a clinically-indicated electrophysiology (EP) study scheduled—a procedure where doctors thread a catheter into your heart to study its electrical signals
- You do not have dextrocardia or mesocardia (abnormal positioning of the heart)
- You do not have a mechanical aortic prosthesis (artificial aortic valve) in place
- You are able to access the femoral artery (groin area) for the catheter procedure

Other trials that look related to this one.
This study looks at how a transcatheter pulmonary valve replacement works in people with repaired Tetralogy of Fallot or double outlet right ventricle. The goal is to better understand the heart’s anatomy and how it may affect the valve procedure.
This trial tests a special catheter to map abnormal heart rhythms like ventricular tachycardia or atrial fibrillation. It may help patients who need a procedure to find and treat the source of these fast or irregular heartbeats.
This study checks whether repeating detailed “electrical mapping” inside the heart can better assess how well catheter ablation is working for an abnormal heart rhythm called ventricular tachycardia. It may help doctors fine-tune treatment plans after your procedure, based on how your heart’s signals change over time.
This trial tests two different ways of mapping the heart to guide treatment for a dangerous fast heart rhythm. The goal is to see which mapping method works better for people with an ICD who need a procedure called ablation to stop the rhythm.
This study checks heart function in children and young adults who had surgery to fix Tetralogy of Fallot. It uses echo, ECG, and Holter monitoring to see how the heart is doing after repair.
This study looks at how blood flow and heart rhythm may affect exercise ability in people born with certain heart defects that have been repaired or treated. It uses a specialized heart MRI and ultrasound measurements to better understand these problems and their causes.
