MRI study of heart rhythm and exercise capacity after congenital surgery
Part of Genetic & congenital, Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a repaired congenital heart condition such as repaired tetralogy of Fallot (TOF)
- You have at least moderate valve leakage seen on ultrasound (PR means a certain heart valve “leak” measured by Doppler)
- Your heart diagnosis fits one of the study’s congenital heart conditions (for example Ebstein’s anomaly, aortic coarctation, Fontan circulation, or certain transposition conditions)
- You can safely have a heart MRI (CMRI)
- You are not currently pregnant

This study uses MRI scans to get detailed images of the heart in infants and children who have or might have congenital heart disease. It aims to help doctors see heart problems more clearly.
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.
