Multiple Arterial Revascularization Using the Tangential K-Graft Technique

The tangential K graft is a comfortable surgical technique aiming to increase cardiac surgeons’ versatility in performing multiple arterial grafting using only two arterial conduits. One end of the free graft—either the right internal thoracic artery (RITA) or the radial artery (RA)—is attached to a marginal circumflex branch. Its other end is anastomosed end to side to a diagonal branch. After the left internal thoracic artery (LITA) is attached to the left anterior descending coronary artery, a wide-open side-to-side LITA to free RITA or RA anastomosis—resembling the letter K—is constructed.
