it seems preductal coarctation of the aorta were the lower part of the body is perfused by poorly oxigenated blood coming from the pulmonary artery via the patent ductus arteriosus... BUT :
Two things bother me:
-patent ductus arteriosus is associated with a "machinery " murmur
- the age. Usually preductal coarctation of the aorta don't survive the neonatal period without surgical correction.

ok...here what i learnt...
PDA is a left to right shunt
when the pressure in the pulmponary vessels increases and the flow reverses...there is a stage when there is a net balance between the left to right ,...and the right to left shunts.....this is when there is no murmur...the only indication for pulm hypertesion is a loud P2
later the right to left shunt predominates...eisenmengers
i hope its clear
