Observational Study for Arrhythmias and Impaired Aerobic Capacity in Congenital Heart Disease

This observational study is looking at how symptoms like shortness of breath and heart palpitations, as well as changes in heart structure, develop in people with congenital heart disease (CHD). Researchers will use remote heart rhythm monitoring for 30 days at the start of the study, and again at 12 and 24 months, to see if it can help find heart problems early. The study is open to adults aged 18 and older with repaired Tetralogy of Fallot (TOF) or other congenital heart diseases like Ebstein's anomaly or Fontan palliation, especially if you have moderate or greater pulmonary regurgitation (PR) based on an echocardiogram. The main goal is to see how the right side of the heart changes over 24 months. The current status of this study is unclear, and it plans to enroll 300 participants.

Study design
This is an observational study, meaning researchers will watch and collect information without giving any new treatments. It plans to include 300 participants.
What's involved
You would participate in remote heart rhythm monitoring for 30 days at the beginning of the study, and again at 12 and 24 months.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 24 months to observe changes in right heart remodeling.
