How is tricuspid atresia diagnosed?
Tricuspid atresia is usually diagnosed with an echocardiogram. An echocardiogram uses high-pitched sound waves that bounce off the child’s heart to produce moving images that the doctor can see on a video screen. The echocardiogram tracks the flow of blood and can show:
- That the tricuspid valve is absent and the right ventricle is smaller than normal.
- How much blood is moving through the holes in the septum.
- Related defects of the heart, including a ventricular septal defect or an atrial septal defect.
