1
Q
Coarctation of aorta
A
Ductus arteriosis doent close properly
Aortic lumen narrows
Left ventricle hypertrophy
Blood flow in lower limbs in weaker - slow femoral pulse
Neonatal emergency
2
Q
Tricuspid atresia
A
No RV inlet
Underdeveloped right ventricle
VSD
Left ventricle hypertrophy
Requires right to left shunt - patent foreman ovale
Blood flow to lungs via the ventricular septal defect or patent ductus arteriosis
3
Q
Hypoplastic left heart
A
- Underdeveloped left ventricle
- Aorta is very small
- RV supports the systemic circulation via PDA
- Requires left to right shunt
