Is four extremity blood pressure indicative of coarctation?
The clinical diagnosis of coarctation of the aorta is initially on characteristic blood pressure findings. The characteristic findings are based on the location of the aorta coarct. Most commonly, systolic hypertension is identified in the upper extremities with diminished or delayed pulses, and low or unobtainable blood pressure readings in the lower extremities. However, systolic hypertension can be identified in the right arm with diminished or delayed pulses in the left arm and the lower extremities (Agarwala, Bacha, Cao, & Hijazi, 2015).
