Tetralogy of Fallot

3D Model

Tetralogy of Fallot is a congenital heart defect that affects four main areas of the heart. One feature of the condition is the incorrect formation of the septum (partition) between the left ventricle (1) and the right ventricle (2). This condition results in mixing oxygenated and deoxygenated blood across the ventricular septal defect (VSD) (3), which causes an overall decrease in the amount of oxygen in the blood. Another feature of tetralogy of Fallot is a narrow pulmonary artery (4). Because the pulmonary artery is narrow or stenotic, it makes it difficult for blood to travel to the lungs to receive oxygen. Another of the defining feature is a misaligned aorta (5). With this condition, the aorta is positioned so that the deoxygenated blood traveling through the VSD flows directly into the aorta instead of the pulmonary artery.
