Can you tell me what "femoral pulses to exclude aortic coarctation" mean?

Coarctation: In coarctation of the aorta, femoral pulses are typically weak or absent with lower blood pressure in the lower extremities. Palpation of femoral pulses does not exclude this diagnosis though; i.e. Pulses are not always absent in aortic coarctation.

Yes: Coarctation of the aorta (coa) refers to a heart defect characterized by a narrowing of the aorta that interferes with blood flow to the lower part of the body. This results in strong pulses in the arms (brachial pulse) but weak or absent pulses in the legs (femoral pulse). The finding of normal femoral pulses makes significant coa unlikely.
