Abstract
Structure abnormalities of the heart or intrathoracic great vessels that arise during fetal development are known as congenital heart disease (CHD). It is the most frequent type of birth defect. Despite great success in surgical and medicinal care of CHD. many operations are palliative rather than curative. and some survivors still have significant residual hemodynamic and electrical conduction abnormalities. as well as long-term cardiovascular problems. The field of congenital heart defect treatment has come a long way in its infancy. With heart problems that were an automatic death sentence 60 years ago, to contemporary surgical survival rates of more than 96 percent for all defects evaluated together. No other branch of research or medicine has done so much in such a short time. In this paper, we overview epidemiology, evaluation and management of congenital cyanotic heart diseases in children.
