How do you assess coarctation of the aorta?
Tests to confirm a diagnosis of coarctation of the aorta may include:
- Echocardiogram. This test uses sound waves to create images of the heart in motion.
- Electrocardiogram (ECG or EKG).
- Chest X-ray.
- Cardiac magnetic resonance imaging (MRI).
- Computerized tomography (CT) scan.
- CT angiogram.
- Cardiac catheterization.
Which artery is enlarged in coarctation of aorta?
Coarctation of the aorta (CoA or CoAo), also called aortic narrowing, is a congenital condition whereby the aorta is narrow, usually in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts….Coarctation of the aorta.

What are the clinical features of coarctation of the aorta?
What are the signs and symptoms of coarctation of the aorta?
- Labored or rapid breathing.
- Weak femoral artery pulse (taken in the groin area)
- Heavy sweating.
- Poor growth.
- Pale or gray appearance.
- Heart murmur: extra heart sound heard when the doctor listens with a stethoscope.
What type of murmur is used for coarctation of the aorta?
The typical heart murmur that is associated with a coarctation is a systolic murmur that is loudest in the back below the left shoulder blade (scapula). If a prominent back murmur is not heard and the child has a blood pressure difference between arms and legs a coarctation located in the abdomen should be considered.
Is coarctation of the aorta cyanotic or Acyanotic?
Congenital heart defects are classified into two broad categories: acyanotic and cyanotic lesions. The most common acyanotic lesions are ventricular septal defect, atrial septal defect, atrioventricular canal, pulmonary stenosis, patent ductus arteriosus, aortic stenosis and coarctation of the aorta.
Where do you listen for coarctation of the aorta?
Auscultation. A continuous “machinery” murmur throughout both systole and diastole or a late systolic murmur is best heard posteriorly over the thoracic spine.
How do you diagnose coarctation of the aorta?
– Electrocardiogram (ECG) – Chest X-ray – Echocardiography – Chest computed tomography (CT or CAT) scan – Magnetic resonance imaging (MRI) of the chest – Cardiac catheterization
What does coarctation of the aorta stand for?
Resection with end-to-end anastomosis. This method involves removing the narrowed segment of the aorta (resection) followed by connecting the two healthy sections of the aorta together (anastomosis).
How does coarctation of the aorta develop?
Disorders of embryogenesis,that is,abnormalities in the development of the fetal aorta during the initial stage of its formation
What is the pathogenesis of coarctation of the aorta (CoA)?
Pathophysiology Coarctation of the aorta imposes significant afterload on the left ventricle (LV), which results in increased wall stress and compensatory ventricular hypertrophy. The afterload may be imposed acutely, as occurs following closure of the ductus arteriosus in neonates with severe coarctation.
