Summary
Children with corrected Fallot tetralogy show reduced exercise capacity and lower maximal heart rate years after surgery. Exercise capacity did not correlate with age at operation or time since surgery.
Area of Science:
- Pediatric Cardiology
- Cardiovascular Physiology
- Congenital Heart Disease
Context:
- Fallot tetralogy is a complex congenital heart defect requiring surgical correction.
- Long-term outcomes and functional capacity after correction are crucial for patient management.
- Exercise testing provides objective measures of cardiopulmonary function.
Purpose:
- To evaluate the exercise capacity and maximal heart rate in children following total correction of Fallot tetralogy.
- To assess the relationship between exercise capacity and factors like age at operation and time elapsed since surgery.
Summary:
- Exercise tests were performed on 21 children, an average of 5 years post-total correction of Fallot tetralogy.
- Maximal exercise capacity, adjusted for body mass and surface area, was approximately 60% of normal values.
- Maximal heart rate achieved during exercise was lower compared to healthy children.
Impact:
- Findings indicate persistent subnormal exercise capacity in children after Fallot tetralogy repair.
- Results highlight the need for continued monitoring of functional status in these patients.
- Lack of correlation with age or time post-surgery suggests other factors influence long-term exercise performance.
