HRHS involves pulmonary valve atresia, hypoplasia of the right ventricle, hypoplasia of the tricuspid valve, and a small, hypoplastic pulmonary artery. As the ductus arteriosus closes postnatally, infants with HRHS become critically ill. UMLS:C0344963 UMLS:C0265856 Underdevelopment of the right ventricle.
