The T-graft utilizes a technique of anastomosing the end of the free right internal thoracic artery (RITA) to the side of the attached left internal thoracic artery (LITA). This procedure assures the attached LITA will always bypass the left anterior descending, the most important coronary artery. Also, the RITA is 10 or 15 cm closer to the posterior circumflex and right coronary artery branches and can almost always reach them. Thus, the entire heart can be completely revascularized with ITA grafts.
