MEDICAL ANIMATION TRANSCRIPT: The treatments for Tetralogy of Fallot are surgical procedures to help fix the following four heart problems. A ventricular septal defect or VSD is a hole in the wall between the two ventricles. An overriding aorta happens when the aorta is located directly over the ventricular septal defect. This means the aorta is connected to both the left and right ventricles instead of its normal attachment to only the left ventricle. In pulmonary stenosis, the main pulmonary artery is narrowed and the pulmonary valve doesn't open all the way. And right ventricular hypertrophy means the wall of the right ventricle is thicker than normal. Tetralogy of Fallot is repaired with open-heart surgery, either soon after birth or in infancy. Surgical procedures may include temporary and complete repairs. Your child may not be ready for a complete repair right away. In this case, a temporary repair such as a shunt or a stent can be placed until a complete repair can be done. Bo...
