Symptoms of Anomalous Coronary Artery (ACA)

What Are the Symptoms of Anomalous Coronary Artery?

The symptoms of ACA vary depending on the type of anomalous artery present. Some types have no associated symptoms and may be found later in life during diagnostic tests such as cardiac echocardiography (echo) or cardiac catheterization. Other types of ACA may cause symptoms related to decreased blood flow to the heart tissue, such as chest pain on exertion or at rest.

Depending on the type of ACA, symptoms may begin in infancy, or, more commonly, they may not appear until later on in life. An older child or adult may complain of chest pain or dizziness and fainting during exertion. Heart failure, with symptoms of shortness of breath on exertion and fluid retention, may be the hallmark symptom if chest pain has been vague or ignored and ischemia (decreased blood flow to the heart muscle) damaged the heart muscle.

Both chest pain and heart failure symptoms serve as early warning signs in adults that the heart muscle is no longer receiving sufficient blood supply from the coronary artery circulation, which may have been adequate during infancy and childhood.

The symptoms of an anomalous coronary artery may resemble other medical conditions or heart problems. Always consult your doctor for a diagnosis.
