Understanding heart issues in patients with congenital heart disease
Official title: Pathophysiologic Mechanism for Arrhythmias and Impaired Aerobic Capacity in Tetralogy of Fallot and Other Congenital Heart Diseases
Run by Mayo Clinic · NCT05122962 · Data updated 2026-11-12
This study is trying to understand what causes symptoms like shortness of breath and palpitations in people with congenital heart disease, especially those with Tetralogy of Fallot, by using remote heart monitoring.

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