| __________ is a congenital heart defect that includes pulmonary stenosis, right ventricular hypertrophy, ventricular septal defect, and an overriding aorta. The clinical signs and symptoms associated with Tetralogy of Fallot are: profound cyanosis at birth with episodes of severe cyanosis and hypoxia, systolic ejection murmur, clubbing of the nail beds, dyspnea, squatting, poor growth, mental slowness, syncope, and cerebrovascular disease. Because deoxygenated (blue) blood can flow directly out to the body, children with this defect often appear bluish.|
Tetralogy of Fallot.
Rationale: The congenital heart defect known as Tetralogy of Fallot is actually a combination of four separate heart defects. It includes pulmonary stenosis, a thickened right ventricle (known as ventricular hypertrophy), a hole between the lower chambers (known as a ventricular septal defect), and an aorta that can receive blood from both the left and right ventricles, instead of draining just the left.
