Severe pulmonary stenosis may impair pediatric right ventricular exercise reserve; hypothesis-generating for compliance-focused longitudinal studies.
How does exercise affect right ventricular hemodynamics in children with varying degrees of pulmonary stenosis?
In children with pulmonary stenosis, severe disease is associated with abnormal right ventricular compliance and suboptimal hemodynamic responses to exercise, driven by myocardial hypertrophy or fibrosis.
Moller et al. (1972) studied this question.
