Tricuspid atresia is one of the least common of the different forms of congenital heart disease .
In this defect the flow of blood from the right atrium to the right ventricle is blocked by an absent or abnormally developed tricuspid valve. This supplies the lungs with some, but less than optimal, blood flow. It also puts a strain on the left ventricle which must now pump both the systemic blood supply and the pulmonary blood supply. Various surgical approaches have been developed and vary depending on the age of the individual at the time the surgery is done.
