tricuspid atresia

Last edited 06/2020

With tricuspid atresia there is no flow between the right atrium and ventricle. The entire systemic venous return enters the left heart via the foramen ovale. The pulmonary circulation is perfused via the ductus arteriosus and/or ventricular septal defects. If the ventricular septum is intact the right ventricle is hypoplastic and pulmonary atresia is present.
