What is Pediatric Aortic Coarctation Follow-Up?

Aortic coarctation is a localized narrowing usually located in the juxtaductal region of the aortic arch (after left subclavian, near ductus arteriosus). It is the 5th-6th most common congenital heart defect (5-8%). Untreated, mortality is 75% within 50 years; even with surgical/catheter intervention, lifelong follow-up is essential. Major associations: bicuspid aortic valve (50-85%), VSD (20-30%), Turner syndrome (10-15%), Berry intracranial aneurysm (10%).

Late complications: 1) Recoarctation - 5-15% (highest risk in infants <1 year), 2) Late hypertension - 30-50% (resting or exercise-induced), 3) Aneurysm/pseudoaneurysm - 5-10% (especially Dacron patch repair), 4) Premature atherosclerosis - LV hypertrophy/diastolic dysfunction, 5) Bicuspid aortic valve - aortic stenosis/regurgitation, ascending aortic aneurysm. Endocarditis, stroke, and aortic dissection are rare but serious.

Follow-up protocol: annual evaluation - physical exam (femoral pulse), 4-extremity BP, ECG, echocardiography (gradient: >20 mmHg = recoarctation suspicion). Cardiac MR/CT angiography every 5 years (every 2-3 years in adulthood). 24-hour ambulatory BP monitoring. Exercise test (exercise-induced hypertension). Lifestyle: BP control, exercise, sodium restriction, endocarditis prophylaxis (high-risk lesions).

Symptoms

Headache and epistaxis (HT)
Lower extremity claudication
Cold lower extremities
Chest pain (rare)
Asymptomatic (often)
Heart murmur (re-emerging)

Risk Factors

Repair at <1 year (recoarctation risk)
Bicuspid aortic valve
Turner syndrome
Family history of CoA
Dacron patch repair (aneurysm)
Postoperative residual gradient

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Annual surveillance (lifelong)
  • New-onset hypertension
  • Difference between upper-lower extremity BP
  • New murmur
  • Headache + epistaxis pattern
  • Pre-pregnancy evaluation

Treatment Methods

01
Annual evaluation (4-extremity BP, ECG, echo)
02
Cardiac MRI/CTA (5-yearly)
03
24-hour BP monitoring
04
Exercise stress test
05
Antihypertensive therapy (recoarctation/HT)
06
Reintervention (recoarctation, aneurysm)
