Cyanotic heart defect

Cyanotic heart defect

A cyanotic heart defect is a group-type of congenital heart defects (CHDs). The patient appears blue (cyanotic), due to deoxygenated blood bypassing the lungs and entering the systemic circulation. This can be caused by right-to-left or bidirectional shunting, or malposition of the great arteries.

Cyanotic heart defects, which account for approximately 25% of all CHDs, include:

Non Cyanotic Heart Defects

Non cyanotic heart defects are more common because of higher survival. In these the shunt is initially from left (oxygenated) to right ( non oxygenated). These are
