“…The vascularization of the RV can also reflect numerous variations in coronary artery origin, tract and distribution. Some can interfere with surgical reconstruction, especially major arterial branches crossing the infundibulum: an aberrant right coronary artery from the pulmonary trunk (Winner et al, ), abnormal origin of the coronary arteries from the pulmonary trunk (Ochos‐Ramirez et al, ), origin of the anterior interventricular artery from the pulmonary trunk (Prost et al ), origin of the left main coronary artery from the right aortic sinus and preinfundibular course, origin of the anterior (or accessory) interventricular artery from the right coronary artery or the right aortic sinus (Canga et al, ), single coronary artery with origin in the left aortic sinus, and a preinfundibular course of the right coronary artery. The numerous coronary arterial variations in congenitally malformed hearts are not discussed in this article.…”

“…Since the left aortic sinus of Valsalva is in closer proximity to the septum of the truncus than to the right sinus [3], a far smaller displacement of the left coronary artery anlage will cause the left coronary artery ostium to fall within the pulmonary artery . Abrikossoff's theory, however, fails to explain those cases in which an accessory (third) coronary artery [6,27], or only one branch of the left coronary artery [1, 12,14,30,40,44], arises from the pulmonary artery . The theory also fails to explain why the relative size of the pulmonary artery, aorta, and their valves has not been found to be altered by displacement of the septum .…”

“…Rarer varieties of partial origin of the coronary arterial system from the pulmonary artery (PA) include origin of an accessory (third) artery from the PA, while the right and left coronary arteries arise normally from the aorta [6,27], origin of the left anterior descending coronary artery from the PA [14,40,44], and origin of the left circumflex coronary artery from the PA [4,30] . TCAPA is the rarest with only 21 cases having been previously reported (Tables I and 2) .…”

“…Origin of a coronary artery from the pulmonary artery is a rare anomaly affecting one in 300,000 live births, 15 % of whom may survive to adult life [ 11. This anomaly usually involves the left coronary artery (LCA), and much less commonly the right coronary artery (RCA). The anomalous origin of one subdivision of the LCA is exceedingly rare, with only one reported case each of the left anterior descending branch (LAD) and the circumflex branch [2,3]. We report the first case of the origin of the anterior descending branch of the LCA from the pulmonary artery to undergo surgical correction and 2-year postoperative angiographic study.…”
