Overview
The signs and symptoms of coarctation of the aorta depend on how much blood can flow through the artery. Children with serious aortic narrowing tend to show signs and symptoms earlier in life, while mild cases may not be diagnosed until adulthood. Common symptoms include: dizziness, syncope, dyspnea, and hypertension.
Symptoms
Symptoms can vary significantly depending on the hemodynamics of the heart. The amount of blood flowing through the artery directly impacts the coarctation site as this may caused pressure and rate of flow differentials. Additionally, the presence of other heart defects or a history of any associated heart defects can also influence the flow of blood in the heart and result in different symptology.
In general, 50% of newborns symptoms will show within the first few days of life. Children with serious aortic narrowing tend to show signs and symptoms earlier in life. In milder cases symptoms may not appear until adolescence. Some people may show no symptoms at all. 80% of all aortic coarctations are diagnosed during a patient's infancy and early childhood.
Common symptoms include:
- Dizziness
- Fainting (syncope)
- Shortness of breath (dyspnea)
- Severe headache most likely due to the presence of hypertension
- Chest pain (angina)
- Cold feet/legs
- Nosebleed
- Leg cramps with exercise
- High blood pressure (hypertension) with exercise
- Decreased ability to exercise
- Poor growth
