Screening Tools for Diagnosis of Congenital Heart Diseases in New born Infants

Abstract

Congenital heart disease (CHD) is a common heart disease, which can be caused by the abnormal development of the heart and blood vessels during embryonic development, or the failure of related channels to close after birth, and it ranks first among all birth defects. There are many types of CHD. Early detection of CHD improves patient outcomes in relation to both morbidity and mortality. screening tests for CHD identification include prenatal ultrasonography and postnatal clinical examination of neonates. screening tool are Pulse oximetry, heart auscultation and echocardiography. Pulse oximetry is a promising alternative newborn screening strategy but further evaluation is needed to obtain more precise estimates of test performance and to inform optimal timing, diagnostic and management strategies.

This review article aims to assess the value of clinical evaluation, Oxygen saturation & blood pressure of four limbs and Echocardiography in early detection of congenital heart diseases.
