Cyanotic Congenital Birth Defects

Congenital heart defects are heart defects that are present at birth. There are many types of congenital heart defects. The American Heart Association states that there are at least thirty-five distinct forms of Congenital Heart Defects. The main types are categorized into either acyanotic or cyanotic categories. Within these two categories are separate types.

What is Cyanotic Heart Disease?

Cyanotic Heart Disease occurs when there is mixing of pure oxygen-rich blood with venous blood. Infants suffering from cyanotic conditions usually have blue nail beds and lips due to the excess deoxygenated blood in their systems. In the cyanotic defects, a shunt bypasses the lungs and delivers venous (deoxygenated) blood from the right side of the heart into the arterial circulation. In general, cyanotic heart birth defects are more complex than acyanotic defects, and have a combination of defects. There are many types of Cyanotic Congenital Defects. The different types are listed below.

Types of Cyanotic Heart Disease

The most common types of cyanotic heart disease are:

  • Tetralogy of Fallot
  • Transposition of the Great Vessels
  • Total Anomalous Pulmonary Venous Return
  • Truncus Arteriosus
  • Tricuspid Atresia
  • Hypoplastic Left Heart Syndrome
