Coarctation of the Aorta

Coarctation of the aorta means there is a narrowed segment in the body’s main artery (the aorta). Because the tube is tighter in one area, the heart must pump harder to push blood through that tight spot. This can raise blood pressure in the upper body (head and arms) and lower the pressure and blood flow to the lower body (abdomen and legs). The narrowing most often sits near the area where a baby’s ductus arteriosus connects to the aorta (the aortic isthmus) just after the left subclavian artery. CoA is usually present from birth (congenital), though rare acquired forms exist. It can appear alone or with other heart findings (especially bicuspid aortic valve). Doctors confirm the problem with heart ultrasound and advanced scans (CT/MRI) and treat it with a catheter procedure (balloon and stent) or surgery when needed. NCBI+2Mayo Clinic+2

Coarctation of the aorta means a narrowed segment in the body’s main artery (the aorta). The narrowing makes the heart pump harder to push blood past the tight spot. Blood pressure gets much higher in the arms and head and lower in the belly and legs. CoA is usually present at birth, but some people are not diagnosed until childhood or adulthood. If the narrowing is tight, babies may get heart failure. If the narrowing is mild, people can grow up and later notice headaches, nosebleeds, leg cramps with walking, or high blood pressure. Treatments are very effective. Options include balloon/stent procedures or surgery. Lifelong follow-up is important because high blood pressure and re-narrowing can happen later.

Other names

People may call it by several names that mean almost the same thing:

• Aortic coarctation / CoA / Aorta coarctation – the standard short and long names. Mayo Clinic

• Aortic narrowing – a plain-language description of the condition. Wikipedia

• Juxtaductal (isthmic) coarctation – describing its usual location near the old ductus arteriosus site. NCBI

• Preductal (infantile) vs. postductal (adult-type) coarctation – older anatomic labels that describe whether the narrowing is before or after the ductus area. NCBI

• Midaortic syndrome / abdominal aortic coarctation – a rarer variant where the narrowing involves the abdominal aorta, sometimes seen in certain syndromes. PMC

Types

1. Classic (discrete) juxtaductal coarctation: a short, tight ring near the aortic isthmus. It makes a clear pressure step-up above vs below the narrowing. NCBI

2. Long-segment coarctation or aortic isthmus hypoplasia: a longer stretch of under-developed aorta, often in infants, which can cause earlier and more serious symptoms. NCBI

3. Arch hypoplasia with coarctation: not only the isthmus but parts of the arch are small; babies can become ill when the ductus closes after birth. NCBI

4. Abdominal coarctation (midaortic syndrome): the narrowing is in the abdominal aorta, sometimes linked with genetic disorders like NF1; it often causes leg or kidney-related blood pressure problems. PMC

5. Associated-lesion patterns (e.g., with bicuspid aortic valve or Shone complex): CoA frequently coexists with a bicuspid aortic valve (BAV) and other left-sided obstructive lesions (Shone complex). This matters because both conditions affect blood flow, blood pressure, and future risks. PMC+2Cleveland Clinic+2

6. Recoarctation (after repair): even after a successful surgery or stent, the aorta can narrow again over time; follow-up imaging and blood pressure checks are important. American College of Cardiology

Clinical note: Every patient with a suspected or known coarctation should have comprehensive imaging (often CT or MRI in addition to echocardiography) to define the anatomy, the length of narrowing, and any collateral vessels. PubMed+1

Causes

Although most cases are congenital (present at birth), it helps to list both common and rare contributors/associations:

1. Congenital maldevelopment of the aortic isthmus: during fetal growth, the tissue near the ductus arteriosus does not form a normal, wide aorta; a tight section remains. This is the most common cause. NCBI

2. Bicuspid aortic valve (BAV) association: many people with CoA also have a BAV. This shared development pathway suggests linked formation problems on the left side of the heart. PMC+1

3. Turner syndrome (45,X): a genetic condition in girls/women that increases risk of CoA and other left-sided heart issues. ScienceDirect

4. Williams syndrome: a genetic condition with elastin gene abnormalities; can cause supravalvular aortic stenosis and may be associated with arch problems and CoA variants. ScienceDirect

5. PHACE syndrome (Posterior fossa anomalies, Hemangioma, Arterial anomalies, Cardiac anomalies including CoA, Eye anomalies): an arterial anomaly syndrome that can include coarctation. ScienceDirect

6. Shone complex: a cluster of congenital left-heart obstructions (including CoA) reflecting broader developmental issues of the left heart outflow tract. Cleveland Clinic

7. DiGeorge/22q11.2 deletion: a chromosomal syndrome linked with conotruncal and arch anomalies, sometimes including coarctation. Cambridge University Press & Assessment

8. Neurofibromatosis type 1 (NF1): can present with abdominal coarctation (midaortic syndrome) due to arterial dysplasia. PMC

9. Familial aortopathy patterns: families with left-sided obstructive lesions and aortopathy may show clustering of BAV and CoA. Screening family members is often advised in BAV/aortopathy. American College of Cardiology

10. Persistent ductal tissue theory: ductal-like tissue extends into the aorta and tightens as the ductus closes after birth, creating a “cinch” at the isthmus. (Embryologic explanation often used in reviews.) NCBI

11. Recoarctation after repair: scar and tissue remodeling after surgery or stenting can re-narrow the aorta later in life. American College of Cardiology

12. Takayasu arteritis (large-vessel vasculitis): an acquired inflammatory disease can cause long-segment narrowing that mimics or produces atypical coarctation, especially in the thoracic or abdominal aorta. PMC+1

13. Fibromuscular dysplasia: non-inflammatory, non-atherosclerotic arteriopathy reported as a cause of acquired atypical coarctation. PubMed+1

14. Atherosclerosis (rare cause for a true “coarctation” but can produce segmental narrowing in older adults): severe plaque can narrow the aorta and mimic obstruction physiology. Mayo Clinic

15. Trauma: severe blunt injury or prior aortic surgery can lead to scar-related narrowing. Mayo Clinic

16. Radiation-related vasculopathy (rare): prior mediastinal radiation may cause large-artery narrowing, potentially involving the aorta. (General aortopathy principle from guideline context.) AHA Journals

17. Infectious aortitis (very rare): infections of the aortic wall can heal with scarring and narrowing. (Pathology texts acknowledge this as uncommon.) AHA Journals

18. Connective tissue disorders with arch involvement: while Marfan/Loeys-Dietz typically cause dilation, some arch development issues may coexist with stenotic segments in congenital contexts. AHA Journals

19. General congenital heart disease clustering: CoA often appears with VSD, PDA, and left-sided obstructive lesions—reflecting broad developmental timing problems. Unbound Medicine

20. Unknown/idiopathic: in many babies there is no single identified external cause; the defect reflects early embryologic variation. NCBI

---

Symptoms

Symptoms depend on age and tightness of the narrowing.

1. High blood pressure (often in arms): the heart pumps against a tight spot, raising pressure above the coarctation; this may cause headaches or nosebleeds later in life. Mayo Clinic

2. Weak or delayed leg pulses: blood struggles to reach the legs; femoral pulses feel late or faint compared with arm pulses. Unbound Medicine

3. Leg cramps or leg tiredness with walking: poor leg blood flow can cause exertional discomfort. MalaCards

4. Headaches: related to upper-body hypertension. MalaCards

5. Shortness of breath or poor feeding in infants: heart strain and poor body perfusion can cause breathing difficulty, sweating, or feeding trouble after ductus closure. Mayo Clinic

6. Poor weight gain in babies: chronic extra heart work and low lower-body flow can limit growth. Mayo Clinic

7. Chest pain or chest tightness: from high afterload and hypertension, especially during exertion. Mayo Clinic

8. Cool legs or feet: lower perfusion below the narrowing. Mayo Clinic

9. Dizziness: sometimes related to blood pressure changes. Mayo Clinic

10. Nosebleeds: a common symptom of uncontrolled hypertension. Mayo Clinic

11. Heart murmur: turbulent flow across the narrowed area can create a systolic murmur, often heard on the back between the shoulder blades. NCBI

12. Cold intolerance in lower body or exercise intolerance: because the legs receive less warm, oxygen-rich blood. NCBI

13. Failure to thrive or lethargy in severe neonatal cases: when the ductus closes, severe narrowing may present abruptly with heart failure signs. Unbound Medicine

14. Claudication-like leg pain: from collateral circulation stress and lower-extremity hypoperfusion in older children/adults. NCBI

15. Signs from associated conditions: e.g., features of Turner syndrome or BAV symptoms (click/murmur), which prompt screening for CoA. American College of Cardiology

---

Diagnostic tests

A) Physical examination

1. Four-extremity blood pressure check: higher pressure in the arms than in the legs suggests a blockage between upper and lower body; a >20 mmHg gradient is suspicious. NCBI

2. Pulse comparison (radio-femoral delay): the wrist pulse (radial) comes clearly before the groin pulse (femoral); this classic delay points to CoA. PMC

3. Auscultation for murmur: a rough systolic murmur is often loudest on the back (interscapular area) due to turbulent flow in the narrowed thoracic aorta. NCBI

4. Signs of hypertension: exam may show upper-body high blood pressure with features like headaches or retinal changes over time. Mayo Clinic

5. Peripheral perfusion check: cool legs, delayed capillary refill in lower limbs, or weak leg pulses indicate reduced downstream blood flow. NCBI

B) Manual/bedside tests

6. Segmental BP measurements with proper cuff sizes: repeating measurements with correct cuffs in both arms and legs prevents false readings and confirms gradients. NCBI

7. Pulse oximetry (pre- and post-ductal in newborns): comparing right-hand (pre-ductal) and foot (post-ductal) oxygen saturation can flag duct-dependent flow issues in infants. NCBI

8. Exercise/cuff test for exertional BP rise: in older children/adults, measuring BP response during light exercise can expose abnormal hypertensive responses seen in CoA. sts.org

9. Careful femoral pulse palpation: repeated careful checks reduce missed diagnoses, especially in neonates where early signs are subtle. Unbound Medicine

10. Bedside Doppler for distal pulses: a handheld Doppler can document weak or delayed femoral flow compared to brachial flow. NCBI

C) Laboratory & pathology

11. Kidney function and electrolytes: long-standing hypertension can affect kidneys; results help guide safety of contrast imaging and overall risk. AHA Journals

12. BNP/NT-proBNP in infants with heart failure signs: elevated values support cardiac strain from severe CoA. NCBI

13. Inflammatory markers (ESR/CRP): in suspected acquired narrowing (e.g., Takayasu arteritis), these markers support an inflammatory cause. PMC

14. Lipid profile: in older adults with suspected atherosclerotic narrowing or co-existing vascular disease. Mayo Clinic

15. Genetic testing/karyotype when indicated: e.g., Turner syndrome work-up in girls/women with left-sided lesions or unexplained CoA. ScienceDirect

D) Electrodiagnostic

16. Electrocardiogram (ECG): may show left ventricular hypertrophy due to pumping against high resistance; rhythm is usually sinus. NCBI

17. Ambulatory (24-hour) blood pressure monitoring: documents masked or persistent hypertension common even after repair. American College of Cardiology

18. Exercise stress testing: evaluates exercise-induced hypertension—an important risk feature in adolescents and adults with repaired or unrepaired CoA. sts.org

19. Pulse oximetry trend monitoring in infants: persistent differential saturation patterns can point to duct-dependent systemic flow. NCBI

E) Imaging (the cornerstone)

20. Transthoracic echocardiography (TTE) with Doppler: first-line in babies and good in many children/adults; it shows the narrowed segment, estimates pressure gradient, and checks associated defects (like BAV). Limitations exist for full arch definition in adults. NCBI+1

21. Cardiac MRI (CMR / MRA): non-invasive, no radiation, excellent for mapping the arch, measuring the narrowing, visualizing collateral vessels, and for lifelong follow-up after repair. It’s a key test recommended in guidelines. PubMed+1

22. CT angiography (CTA): fast, detailed 3-D anatomy; very helpful pre-intervention or for stent surveillance, though it uses radiation and contrast. AJR American Journal of Roentgenology+1

23. Chest X-ray: classic, supportive signs include rib notching (from enlarged intercostal collaterals) and the “figure-3 sign” (pre-stenotic bulge, the indentation, and post-stenotic bulge). These clues prompt definitive imaging. AHA Journals+2Radiopaedia+2

24. Catheter angiography: now mainly used when planning and performing treatment (balloon, stent) but still the invasive gold standard for detailed pressure measurements and anatomy when needed. PubMed

25. Fetal echocardiography (during pregnancy): can sometimes detect arch hypoplasia/coarctation risk before birth, helping plan delivery and early care. PubMed

Guideline pearls: Adults with a bicuspid aortic valve should be evaluated for coarctation; after repair, periodic cross-sectional imaging (CMR/CTA) and blood pressure monitoring are recommended. Screening for intracranial aneurysms may be reasonable in adults with coarctation. American College of Cardiology+1

2) Surgical resection with end-to-end anastomosis
What: surgeon removes the narrow segment and stitches the two ends together.
Why: preferred in infants/some children and in complex anatomy not ideal for stents; durable relief. JACC

3) Extended end-to-end repair / arch augmentation
What: enlarges a long hypoplastic arch segment.
Why: corrects long under-grown arch when a simple cut-and-join is not enough. JACC

4) Patch aortoplasty
What: a patch of synthetic or biological material widens the narrowed area.
Why: used in select anatomies or redo operations; balancing dilation versus aneurysm risk. JACC

5) Interposition graft or bypass
What: diseased segment replaced with a graft or bypassed.
Why: adults with complex or recurrent narrowing, prior surgery, or aneurysm. Requires lifelong imaging. AJR American Journal of Roentgenology

FAQs

1) Is coarctation of the aorta curable?
Most people get excellent results after stent or surgery, but lifelong follow-up is needed for BP and re-narrowing checks. American College of Cardiology

2) How is CoA found in adults?
Unequal arm-leg BP, weak leg pulses, and imaging (echo + MRI/CT) confirm it. Mayo Clinic+1

3) What gradient means “significant”?
Clinically, a peak-to-peak gradient ≥20 mmHg (or lesser with other signs) often prompts treatment; invasive confirmation is standard when planning interventions. revespcardiol.org

4) Stent or surgery—what is better?
For many teens/adults with suitable anatomy, stenting is first choice; surgery is best for certain arch shapes or infants. Both have excellent outcomes. PMC+1

5) Will my blood pressure be normal after repair?
It often improves, but exercise-induced or masked hypertension can persist; keep monitoring and continue therapy if needed. American College of Cardiology

6) Can I lift weights?
Light-to-moderate dynamic resistance is usually fine, but avoid heavy isometric straining, especially if the aorta is enlarged. Get a personalized plan. www.heart.org

7) Do I need MRI or CT if my echo is normal?
Yes—at least once, and periodically after repair, to see the whole aorta and any stent or patch. Medscape

8) Are there medicines specific for CoA?
No specific drug fixes the narrowing. Medicines control BP and wall stress before/after the mechanical repair. Medscape

9) Is pregnancy safe?
Many women do well with careful planning in an ACHD program; unrepaired tight CoA carries risk. Pre-pregnancy assessment is key. PMC

10) Do I need endocarditis prophylaxis?
Only in specific situations (e.g., certain prosthetic materials and procedures). Your ACHD team will advise. JACC

11) Could CoA come back?
Re-coarctation can occur, especially in younger repairs or certain techniques; that is why surveillance never stops. American College of Cardiology

12) Do all patients need brain artery screening?
