What is Anomalous Left Coronary Artery from the Pulmonary Artery?

Also known as: ALCAPA, anomalous left coronary artery, ALCA

In a normal heart, the left coronary artery starts in the aorta (the blood vessel that transports blood with oxygen from the heart to the rest of the body including the heart). In babies who are born with ALCAPA, this artery starts at the pulmonary artery, (the artery that takes blood that needs oxygen to the lungs) which means that the heart muscle doesn't get enough oxygen.
