Panel A: CT image of a left main with a prepulmonic course; panel B: CT image of a left main with a subpulmonic course; panel C: CT image of a right coronary artery with an interarterial course; panel D: angiographic view of a circumflex artery with a retroaortic course. Dotted lines indicate the border between the proximal and distal segments.
