Coarctation of the aorta typically presents with which blood pressure pattern?

Explanation:
Coarctation of the aorta creates resistance to blood flow to the lower body, so the pressure proximal to the narrowing rises while distal pressure falls. This produces a pattern where the upper extremities have higher blood pressure than the lower extremities, often with delayed or weak femoral pulses. In practice, measuring blood pressure in all limbs and noting a significant arm–leg gradient (typically more than about 20 mmHg) supports this diagnosis.
