What are the symptoms of tricuspid atresia?
Since there is mixing of both pure and impure blood in the heart and that blood causes into the body, the child may appear blue. Some children may have too much blood flowing into the lungs through the hole in the ventricles and this could lead to breathlessness. Since the heart has to function more to supply adequate oxygen to the body, there may be heart failure and growth retardation.

How is tricuspid atresia diagnosed?
The diagnosis is made by echocardiography.

What are the other problems associated with tricuspid atresia?
About 15-20% of patients with tricuspid atresia may have other heart defects. Sometimes pulmonary valve (valve that regulates flow from right ventricle to the lungs) may be absent and volume of blood reaching the lungs may be low and thus less blood will get oxygenated leading to increased bluish colour of skin. Some patients have problems of the arteries.
