Isolated right ventricular hypoplasia.
Hypoplasia of the right ventricle, unassociated with severe pulmonary or tricuspid valvar malformations, is a primary congenital abnormality in which the trabeculated sinus portion of the ventricle fails to develop. An atrial septal defect or a stretched foramen ovale serves as an escape valve. The clinical, hemodynamic, and angiocardiographic features of this rare type of cyanotic heart diseas...
متن کاملTransient and anatomic isolated right-ventricular hypoplasia.
To the Editor Isolated right-ventricular hypoplasia (RVH), not associated with severe pulmonary or tricuspid valve malformations, is an uncommon congenital abnormality characterized by a failure in the development of the ventricular trabecular sinus portion, which is therefore absent or marked attenuated. Consequently, the tricuspid valve may be abnormally small or frankly obstructive. An assoc...
متن کاملIsolated left ventricular apical hypoplasia.
the apex of the right ventricular cavity as the left intraventricular pressure increases. Differential diagnosis of this pathology requires the presence of left ventricular hypoplasia, aneurysms and ventricular diverticula. The ventricular hypoplasia is characterized by a small and hypertrophic ventricular chamber and dysplastic cardiac valves. The diverticul originates on the ventricular wall ...

متن کاملIsolated right ventricular hypoplasia with atrial septal defect or patent foramen ovale.
IN 1936, Taussig1 stated that a diminutive right ventricle is always associated with underdevelopment or malformation of the tricuspid or pulmonic valves. Four cases of hypoplastic right ventricle unassociated with valvular defects have been reported in recent years. A patent foramen ovale or atrial septal defect has been an accompanying anomaly. All cases have been described in cyanotic infant...
