title: [Ectopic connection of the left coronary artery with the contralateral sinus with or without intramural pathway: how and why differentiating them?].
abstract: Among the wide spectrum of congenital abnormalities of coronary arteries, a left coronary artery connected with the contralateral sinus is considered as an anatomical high-risk while associated with a proximal preaortic course. The ectopic connection may be associated with or without intramural pathway regarding the aortic wall. An intramural pathway is a characteristic to be considered because it is able to be involved in myocardial ischemia-related adverse events of which the sudden death. Therefore, making an identification of an intramural pathway is essential for the ectopic connections of the left coronary artery associated with a preaortic course.
