A diagnosis of TOF is usually made with echocardiography, which can even be done prenatally. Most patients with tetralogy of Fallot will have cardiac repair surgery in the first year of life, where the ventricular septal defect is closed with a patch, and the right ventricular outflow tract is enlarged.
Tetralogy of Fallot (TOF), formerly known as Steno-Fallot tetralogy, [9] is a congenital heart defect characterized by four specific cardiac defects. [4] Classically, the four defects are: [ 4 ] pulmonary stenosis , which is narrowing of the exit from the right ventricle;
Time of flight (ToF) is the measurement of the time taken by an object, particle or wave (be it acoustic, electromagnetic, etc.) to travel a distance through a medium. This information can then be used to measure velocity or path length, or as a way to learn about the particle or medium's properties (such as composition or flow rate).

The collaterals continue to grow, and can become the main supply of blood to the lungs. Though it is usually associated with congenital heart diseases with decreased pulmonary blood flow, like tetralogy of Fallot or pulmonary atresia, it may be seen sometimes in isolation (i.e. not associated with any congenital heart disease).
An overriding aorta is a congenital heart defect where the aorta is positioned directly over a ventricular septal defect (VSD), instead of over the left ventricle. [1] The result is that the aorta receives some blood from the right ventricle, causing mixing of oxygenated and deoxygenated blood, and thereby reducing the amount of oxygen delivered to the tissues.
Time of arrival (TOA or ToA) is the absolute time instant when a radio signal emanating from a transmitter reaches a remote receiver.The time span elapsed since the time of transmission (TOT or ToT) is the time of flight (TOF or ToF).
Pulmonary bay is a medical term which describes a finding on the chest radiograph. In pulmonary bay, there is a concavity where you would normally find the pulmonary artery. Pulmonary bay is most commonly associated with tetralogy of Fallot, however it may also be seen in other conditions where there is a reduced outflow from the pulmonary ...
