Abstract
Tricuspid atresia (TA) is a type of cyanotic congenital heart defect (CCHD) characterized by complete obstruction of the atrioventricular valve associated with the morphologic right ventricle. It is an archetypal lesion representing single-ventricle physiology. It is the third most common CCHD. The definition, embryology, presentation, diagnostic assessment, and management of tricuspid atresia are discussed. This lesion represents a gamut of variations in anatomy and physiology requiring the cardiac team to palliate these patients using many different techniques and strategies to obtain the goal of a total cavopulmonary connection. Because the systemic ventricle is the morphologic left ventricle, patients with TA tend to have a good prognosis when compared with other single-ventricle lesions.
