Coronary ectopic origin

Coronary ectopic origins are common in the pulmonary and aortic origins, and common in the common carotid and innominate arteries are extremely rare and often accompanied by severe heart malformations. Brooks first reported two patients in 1885. The most common ectopic origin of the pulmonary artery is the left coronary artery. In addition, there is a rare right coronary artery that originates from the pulmonary artery. Both bilateral coronary arteries originate from the pulmonary artery. The left coronary artery circumflex branch originates from the pulmonary and accessory coronary or conical coronary Originating from the pulmonary artery. Both coronary arteries originate from the pulmonary arteries and die a few days after birth due to severe myocardial ischemia and hypoxia, which is rarely diagnosed clinically. The left coronary arteries originate from the pulmonary artery. The left coronary artery originated from the pulmonary artery, but its branch distribution and behavior were normal. Its incidence rate was only 1 in 300,000 live babies, and it accounted for 0.26% of congenital heart disease.
