Abstract:
Our patient was diagnosed with complete atrioventricular canal and Tetralogy of Fallot with pulmonary atresia at the age of 1 month. Then he underwent right and left Blalock-Taussig shunts at the ages of 2 months and 5 years, respectively. His cyanosis had increased at 20 years of age. Cardiac catheterization showed occlusion of the left Blalock-Taussig shunt and absence of the left pulmonary artery. Lung perfusion scintigram showed late phase perfusion in the left lung. Chest computed tomographic scan demonstrated the left pulmonary artery. We describe the operative technique of total correction.

Mitral Stenosis I: Introduction
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...
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...
