VSD-overriding aorta: Tetralogy of fallot is a congenital heart anomaly consisting of ventricular septal defect, right ventricular hypertrophy, pulmonary stenosis and aortic override of the vsd. It causes blue spells in undiagnosed neonates from poor blood oxygenation. It accounts for 5-10% of all congenital cardiac defects and is typically sporadic and non-syndromic. 15% of cases have aneuploidy (down) or digeorge.

TOF: A type of congenital (present at birth) heart disease that usually causes cyanosis (blue baby). It is characterized by a large hole in the heart (vsd) and obstruction of blood flow to the lungs (pulmonary stenosis). Babies born with tof require surgery during infancy.

TOF: Tetrology of Fallot is a congenital heart defect consisting of defect in the wall between the ventricles, stenosis of the pulmonary artery, enlargement of the right ventricle, and an abnormally placed aorta. It occurs in about 5 out of every 10,000 babies. The defect affects boys and girls equally. It is corrected with open heart surgeries.

Congenital heart dis: This is a congenital heart defect knows at "tetralogy" because the initial description discussed four findings: 1) ventricular septal defect, 2) overriding aorta, 3) pulmonary stenosis, 4) right ventricular hypertrophy. The cause is abnormal conotruncal septation, giving too much to the outflow to the aorta and not enough to the outflow to the lungs. This defect always requires surgical repair.

Is tetralogy of fallot hereditary?

Dr. Steven Neishanswered

In some families: In some families, there are genetic factors that affect the development of various conotruncal heart defects, which includes tetralogy of fallot. One gene defect that can result in tof is 22q deletion. There is variability in both penetrance (does the disease show up) and expression (the exact way a disease occurs.).

Could tetralogy of fallot be genetic?

Yes: Definitely, some cases of tetralogy of fallot have a genetic component. For instance, in 22q deletion syndromes (digeorge syndrome) one of the common heart diseases is tetralogy of fallot and variants of tetralogy of fallot.
