Abstract

Cyanotic heart defect is a group-type of congenital heart defect (CHD) that occurs due to deoxygenated blood bypassing the lungs and entering the systemic circulation or a mixture of oxygenated and unoxygenated blood entering the systemic circulation. It is caused by structural defects of the heart (i.e.: right-to-left, bidirectional shunting, malposition of the great arteries), or any condition which increases pulmonary vascular resistance. The result being the development of collateral circulation.

Diagnosis | Types

According to a study in cyanotic congenital heart disease (CCHD) in Sohag University, Upper Egypt. 50 neonates were diagnosed as suffering from cyanotic congenital heart disease (CCHD), they concluded that cyanotic congenital heart disease (CCHD) frequency was significant (9.5%) with D-TGA being the commonest type. Majority of neonates with Cyanotic congenital heart disease (CCHD) showed survival with suitable management.
