Congenital heart disease (CHD) can be benign and not require any treatment or life threatening requiring immediate life shaving action.
The worrisome group of heart diseases are the ‘duct’ (PDA) dependent CHD lesions most often presenting in the neonatal period. These conditions are often asymptomatic in the early stages but may be detected by routine post-natal oxygen concentration assessment at birth or Day 1. The other assessment includes presence of a soft murmur (abnormal sound from the heart), poor pulses (especially lower limbs), fast breathing (tachypnoea), fast heart rate (tachycardia) or a very active chest wall movement.
Duct dependent lesions are divided into Right heart lesions such as Transposition of the Great Arteries, Tetralogy of Fallot, Pulmonary Atresia/Stenosis and Left heart lesions such as Hypoplastic Left Heart Syndrome, Coarctation of the Aorta, Critical Aortic Stenosis/Interrupted Aortic Arch.
Right heart lesions present with cyanosis (blue discolouration of body / lips) and left heart lesions with heart failure.
