The blood pressure characteristics of aortic stenosis should be characterized by elevated blood pressure due to aortic constriction, which is characterized by significant differences in blood pressure in the upper and lower extremities, being higher in the upper extremities than in the lower extremities by more than 20 mm Hg, often exceeding 40 mm Hg. Aortic constriction is a narrowing of the aorta, most commonly at the distal part of the left subclavian artery branch at the arterial catheter junction. Aortic constriction is often associated with extensive arterial disease and aortic valve and mitral malformations. The more typical symptoms are systolic hypertension in the upper extremities or systolic vascular murmurs, and severe aortic constriction can also lead to cardiac insufficiency, heart failure or even cardiogenic shock.
