The 5 T's of Congenital Heart Disease refer to the five cyanotic heart defects that cause early cyanosis (blue baby syndrome) due to right-to-left shunting of blood. They are:
Tetralogy of Fallot (TOF) – A combination of four heart defects leading to reduced oxygenation.
Transposition of the Great Arteries (TGA) – The aorta and pulmonary artery are switched, leading to improper circulation.
Truncus Arteriosus – A single large vessel arises from the heart instead of separate pulmonary and aortic arteries.
Total Anomalous Pulmonary Venous Return (TAPVR) – Pulmonary veins drain into the right atrium instead of the left, causing mixing of oxygenated and deoxygenated blood.
Tricuspid Atresia – Absence of the tricuspid valve, blocking blood flow from the right atrium to the right ventricle.
