Heart Differential Cyanosis seen only in PDA

acc. to UW,


differential cyanosis of lower extremities occur only due PDA,


they are refusing aortic coarctation as the answer by giving two reasons:

1) infantile preductal: associated with PDA and never gng to survive beyond infancy.

2) adult postductal: coarctation is never severe enough to cause cyanosis...


what is this???
