SURVIVAL RATE AFTER THE REPAIRING OF TETRALOGY OF FALLOT

Abstract

Nowadays there is lot of complications has grown in which our heart is the primary organ of body that get affected. As the embryo grows in the womb of mother, during embryogenesis phase few changes has happened that changes the entire structural and functional capacity of heart. Defects that came with the birth of child is called is called as congenital heart defects as they came with the infant when he/she is born. Congenital heart defects also known as birth defect. Congenital heart defects divide into ACYANOTIC and CYANOTIC. ACYANOTIC divides into left to right shunts and outflow obstruction. In left to right shunt is VSD, PDA, ASD and in outflow obstruction is pulmonary stenosis, aortic stenosis, Coarctation of aorta. In CYANOTIC is Tetralogy of Fallot and transposition of the great arteries. For repairing of TOF there is two methods or techniques that is used to correct TOF those are open heart surgery and temporary method (BT shunt). Open heart surgery involves closure of VSD using Dacron patch and BT shunt is temporary fix that is used to improve the blood flow in pulmonary circulation.
