Coarctation (CoA) of the aorta is when the main body artery narrows, impairing the blood supply to the lower half of the body.
Diagnosis and treatment for babies is based on clinical findings (such as weak pulses in the legs) and echocardiography. Typically treatment is surgery, but occasionally heart catheterisation may be the treatment of choice.
In older children, diagnosis is based on clinical findings (such as weak pulses in the legs and high blood pressure), echocardiography and MRI. Treatment depends on the type of lesion.
Surgery may be recommended, but in teenagers and adults, interventional heart catheterisation is usually the preferred treatment.
