What this trial studies

This observational study aims to identify the mechanisms that lead to symptoms such as shortness of breath and palpitations in patients with congenital heart disease, particularly those with Tetralogy of Fallot. It will utilize remote heart rhythm monitoring to gather data on heart structure and function. By analyzing these factors, the study seeks to improve understanding of how these conditions affect patients' health and quality of life.

Who should consider this trial

Good fit: Ideal candidates include individuals with repaired Tetralogy of Fallot or other congenital heart diseases who exhibit moderate or greater pulmonary regurgitation.

Not a fit: Patients who are pregnant or unable to undergo cardiac MRI will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better management and treatment strategies for patients with congenital heart disease.

How similar studies have performed: Other studies have shown success in understanding arrhythmias and heart function in congenital heart disease, making this approach promising.
