Can anyone tell me what's the auscultation-related sign of the aortic coarctation? i hear a thick harsh systolic sound in the aorta area. is it?

Coarctation: There may be a click or systolic ejection murmur over the aortic area, but that would be related to a bicuspid AV, which can occur with the coarctation. The most common and indicative findings are hypertension or elevated pressures in the upper extremities with lower pressure and diminished pulses in the lower extremities. The actual findings depend on the location of the narrowing.
