Description
Summary:	This report describes a new system to facilitate the identification of coronary artery bypass grafts during repeat coronary angiography. Geometric markers (square, triangle, circle, hexagon) are placed over the aortic end of the graft, with each geometric shape designating the target vessel of the graft, e.g. square, right coronary; triangle, anterior descending. This system significantly simplifies cannulation of the postoperative patient and also allows immediate recognition of specific vessels bypassed by mere perusal of the chest film.
