Characteristic murmurs and sounds on auscultation (eg, continuous or late systolic murmur posteriorly over the thoracic spine, bilateral collateral arterial murmurs, aortic ejection sound, short midsystolic murmur, or early diastolic murmur of aortic regurgitation)
Beyond infancy: Usually none; however, hypertension, headache, nosebleed, leg cramps, muscle weakness, cold feet, or neurologic changes may be seen
Frequently normal physical appearance (except when coarctation compromises the origin of the left subclavian artery or in cases of XO Turner syndrome)
Early life: Congestive heart failure, severe acidosis, or poor perfusion to the lower body.
Associated cardiac defects (eg, left-side obstructive or hypoplastic defects and ventricular septal defects, bicuspid aortic valve, aortic arch hypoplasia, and, rarely, various right-side cardiac obstructive lesions)
Abnormal differences in upper- and lower-extremity arterial pulses and blood pressures; diminished and delayed pulses distal to obstruction
