Coding of coronary arterial origin and branching in congenital heart disease: the modified Leiden Convention

Variations in coronary anatomy are common and may relate to the position of the coronary ostium relative to the aortic sinus, the angle of coronary take off, or the course of the coronary arterial branches. Several classification systems have been proposed. However, they all lack a simple rationale that is applicable irrespective of the relative position of the great arteries, as well as in bicuspid aortic valves. Here, we present a modification of a relatively simple system introduced in the early eighties, designated the “The Leiden Convention“.
