blood exiting the heart meets an area of narrowing

• coarctation of the aorta, aortic stenosis, pulmonary stenosis

coarctation of the aorta

• elevated BP in arms

• weak femoral pulses

• cool lower extremities

• complaints of leg fatigue

might want to keep PDA open

aortic stenosis

aortic stenosis s/s:

• weak pulses

• irregular heart rhythm
