QUOTE FOR WEDNESDAY:

“Tetralogy of Fallot (TOF) is a congenital heart defect with four components: 1) large ventricular septal defect (VSD), which is a hole between the two ventricles or pumping chambers in the heart; 2) pulmonary stenosis, which is narrowing beneath or in the blood vessel leading to the lungs; 3) overriding of the aorta, in which the aorta lies directly above the ventricular septal defect; and 4) as a result of these events, the right ventricle becomes thickened or hypertrophied.”
