This disease is called the coarctation of the aorta, i.e. that the vessel which come out the heart (aorta) is obstructed, which reduces the blood-flow and raises the blood pressure in the upper limbs.

Thus, the doctor sees a rise in the blood pressure only in the arms, but not in the lower limbs. The aorta makes a noise (a " murmur") when the doctor listens it with his stethoscope.

Its treatment is only instrumental and is based on the dilation of the artery by a per-coetaneous device.
