2. Fig 1
The construction of the “π” graft. (Left) The “Y” graft: (1) the left internal thoracic artery (ITA); (2) the right ITA; and (3) the “Y” anastomosis at the level of the pericardial reflection on the pulmonary trunk. (Middle) The “Y” and the mammary loop: (4) loop anastomosis at a variable level on the right ITA; (5) the loop will be cut open at the appropriate level. (Right) The “π” graft: (6) the left branch made with the left ITA, going to the left anterior descending artery; (7) the middle branch made with the reversed left ITA going to the lateral ventricular wall vessel(s); and (8) the right branch made with the right ITA going to the right coronary artery territory.
