This document provides information about Tricuspid Atresia, a congenital heart defect where the tricuspid valve is absent or closed. Key points include: - Babies born with this condition require holes between the atria and ventricles, or a patent ductus arteriosus, to allow blood to reach the lungs. Multiple surgeries are usually needed like shunt procedures or Fontan operations. - Symptoms appear soon after birth and include blue skin color, breathing difficulties, and heart murmurs. Diagnosis involves various tests like echocardiograms. - Long term, children may develop issues like heart rhythm problems, valve leaks, or endocarditis which are monitored lifelong
