Abstract:
Untreated, the prognosis for patients with tricuspid atresia (TA) is poor. Recent advances in medical and surgical therapy, particularly the application of Fontan principle, have markedly improved the long-term outlook for children with this condition. Palliative procedures to normalize the pulmonary blood flow and to relieve interatrial or interventricular obstruction should be undertaken promptly. Staged total cavopulmonary connection to bypass the right atrium and right ventricle by an initial bidirectional Glenn procedure and followed by extracardiac conduit diversion of inferior vena caval flow into the pulmonary arteries appears to be the current procedure of choice in the surgical management of TA. Total cavopulmonary diversion appears to be superior to conventional Fontan-Kreutzer operations, but long-term follow-up results are needed to confirm this impression.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
