VI. COARCTATION OF THE AORTA
After correction of the coarctation, the blood pressure may increase over the ensuing years. Thus close follow up is necessary. Because constriction of the aorta causes reduced blood flow to the kidney, the renin–angiotensin system is stimulated and this increases blood pressure. ACE inhibitors constitute rational therapy for the manage¬ment of hypertension, but are not always successful.
