Tricuspid atresia

Illustration showing tricuspid atresia

In tricuspid atresia, blood can't flow from the right atrium to the right ventricle because the valve between them is missing. This condition often includes a smaller than normal right ventricle, as well as an atrial septal defect and, in some cases, a ventricular septal defect.
