Is a smaller right ventricle associated with poorer exercise performance in young patients with repaired Tetralogy of Fallot?
In young patients with repaired Tetralogy of Fallot and pulmonary insufficiency, a smaller right ventricle is associated with worse exercise performance, representing a unique pathological entity independent of RV dilation.
A smaller RV was associated with worse exercise performance, indicating exercise intolerance is independent of RV dilatation in young rTOF with PI and represents a unique pathological entity responsible for reduced exercise performance.
Mhanna et al. (Mon,) studied this question.
