Tetralogy of Fallot: Why Surgery is Sometimes Necessary?

Tetralogy of Fallot, also known as TET-AL-O-JEE of fallot, is a congenital heart defect in which four heart abnormalities are present at birth. These abnormalities include a large hole between the upper chambers of the heart (the atria) and the lower chambers (ventricles), as well as an obstruction of blood flowing from the heart out to the lungs, which causes oxygen-poor blood to back up into the lungs and bloodstream. This can lead to several complications later in life, including arrhythmias, or heart rhythm disturbances. What Is Tetralogy of Fallot? Tetralogy of Fallot, or TOF, is a rare heart condition that affects the right ventricle and pulmonary artery. The four different parts to this condition are pulmonary stenosis (narrowing), ventricular septal defect (hole in the wall between the two lower chambers), over-riding aorta (the largest artery in the body), and right ventricular hypertrophy (thickening). Those with TOF have a higher risk for developing pulmonary hypertension. T...
