heart defect at birth - congenital

heart defects at birth can be grouped into electrophysiological defects, structural defects or functional defects. It affects 1 in 125 births.


2types:
a) cyanotic heart disease
b) non-cyanotic heart disease

cyanotic heart disease:-
a) Triology of Fallot, Eisenmenger, Ebstein's anomaly (Right Ventricular enlargement)
b) Tricuspid atresia (Left Ventricular enlargement)
c) Transposition of the great vessels & truncus arteriosus (biventricular enlargement)
d) Tetralogy of Fallot ( no ventricular enlargement)

non-cyanotic heart disease
a) Atrial septal defects, pulmonary stenosis (Right Ventricular enlargement)
b) Patent ductus arteriosus, coarctation, Aortic stenosis (Left Ventricular enlargement)
c) Ventricular septal defect (biventricular enlargement
d) any mild lesion or dextrocardia ( no ventricular enlargement)

+Aortic stenosis, coarctation of the aorta and pulmonary stenosis are not associated with shunting of blood from the left side to the right.


Commonest : Ventricular Septal Defects (VSD) - 1/5 of all congenital heart defects
