  1. The Right side of the heart: It collects deoxygenated blood from the whole body then pumps it to lungs for gaseous exchange
  2. The Left side of the heart: It collects oxygenated blood from the lungs and then pumps it to the whole body for tissue oxygenation.

They are as follows[/vc_column_text][vc_column_text]

a. Inheritance

> HCM, ASD, Supravalvar A.S – Autosomal dominant
> Marfan’s with cardiac involvement- Autosomal dominant
> Holt – Oram syndrome with heart lesion (V.S.D) – Autosomal dominant
> Noonan’s with heart lesion – Autosomal dominant

b. Chromosomal Aberration

> 40% of Down’s syndrome have CHD (AV canal, TOF, VSD.)
> 20% of Turner’s have coarctation of the aorta or aortic stenosis

c. Maternal use of drugs during pregnancy

> Alcohol causes – TGA, VSD, PDA
> Amphetamine – TGA, VSG, PDA
> Phenytoin – PS, AS, COS, PDA
> Lithium- Ebstein anomaly
> Sex-hormones – TGA, TOF, VSD

d. Infections

> TORCH infections cause Pulmonary stenosis, Patent ductus arteriosus, Endocardial fibroelastosis.

e. Maternal conditions

> Maternal Diabetes mellitus causes – hypertrophic cardiomyopathy|
> Systemic Lupus erythematosus causes heart block in a baby.
