tricuspid atresia
a rare form of congenital heart disease in which there is no communication between the right atrium and the right ventricle. Affected babies present with cyanosis, breathlessness, particularly on feeding, and failure to thrive. Diagnosis is by echocardiography. Treatment involves surgical intervention, but the prognosis is often poor.
