Coronary artery abnormality originates from pulmonary artery

Coronary arteries originated from the pulmonary arteries refer to 1 coronary artery or its branch (left anterior descending coronary artery or left circumflex coronary artery) or 2 coronary arteries originated from the proximal pulmonary artery trunk or very few originate from the proximal right pulmonary artery. During normal development, the pulmonary artery trunk also grows coronary artery buds, but usually degenerates and disappears. The left or right coronary artery plexus is not connected to the aortic sinus buds, and abnormally connected to the pulmonary artery buds, the coronary artery abnormality originates from the pulmonary artery.
