Table 4.22 - Coarctation of the Aorta.
- Obstruction due to concentric narrowing of the distal aortic arch; usually just beyond the left subclavian artery; produces pressure gradient between ascending and descending aorta.
- Increasing enlargement of chest wall arteries allows flow around the obstructive area.
- Increasing hypertension in the central aorta occurs with age (may lead to blindness), imposing severe afterload on the LV, with resultant enlargement (see with ECG).
- See increased blood pressure and pulses in upper body, with absent or diminished leg pulses.
