Congenital Heart Defect’s (CHD) affect about 1% of all births in the United States or about 40,000 babies per year ( Tetralogy of Fallot (TOF) is a CHD that accounts for an estimated 10% of these births. There are many factors that are involved in the diagnosis, treatment and quality of life for these children. The effects of the CHD vary in severity, therefore the effects it has on a child’s life vary. The etiology of TOF, how specific organs, cells, and tissues are affected, and what organ systems are affected will all be discussed and explained. . The effects vary greatly between patients this paper will focus on the average effects of this condition in order to provide a better understanding of TOF.
TOF is a CHD which means the abnormal development of the heart occurred during gestation .A normal heart consists of four chambers of cardiac muscle cells, four heart valves, an electrical pathway, and its own blood supply. The chambers are the Right Atrium (RA) , Right Ventricle ( RV), Left Atrium,(LA) , and the Left Ventricle ( LV). The blood flows from the Vena Cava to the RA thru the Tricuspid Valve to the RV. It then gets ejected thru the Pulmonary Valve into the Pulmonary Artery, and on into the lungs. It returns to the LA, goes thru the Mitral Valve into the LV, and then is ejected thru the Aortic Valve into the aorta and onto systemic circulation. TOF is identified by four atypical finding within the heart.
