The results are reported of a study of 83 necropsied hearts with atresia of the right atrioventricular orifice. It is emphasised that right atrial or atrioventricular orificial atresia is a better term to describe this anomaly than "tricuspid atresia". Use of the latter term can be confusing when the morphologically tricuspid valve is located beneath the left atrium. It is accepted that the def...

The present report describes a male newborn with a pulsatile structure beneath the sternum. Echocardiography showed common atrium, a single ventricle, mitral atresia, double outlet right ventricle, subpulmonary stenosis, small pulmonary artery branches, and a thin walled ventricular diverticulum suggestive of Cantrell's syndrome. The diverticulum was resected to prevent life threatening events ...

Definition of “functionally single ventricle” includes a wide spectrum of anatomical variants such as double inlet left or right ventricle, mitral or tricuspid atresia, unbalanced atrioventricular canal, heterotaxy syndrome with one normally developed ventricle or other congenital heart defects with severe hypoplasia of one of the ventricles [2]. Anatomical and hemodynamic abnormalities in thes...
