2. Fig 1
Y composite graft. The radial artery (RA) shows kinking when the RA as a Y composite graft is sewn on the diagonal (DG) that runs parallel to the left anterior descending artery (LAD) in a side-to-side fashion. (LITA = left internal thoracic artery; OM = obtuse marginal.)

3. Fig 2
K composite graft. The advantage of the K graft is sparing the length of the radial artery (RA), when bypass is necessary for the diagonal (DG) that runs parallel to the left anterior descending artery (LAD). (LITA = left internal thoracic artery; OM = obtuse marginal; PD = posterior descending; PL = posterolateral.)

4. Fig 3
X composite graft. In an X graft, the radial artery (RA) can extend fully around the heart from the diagonal (DG) to the posterior descending (PD) artery. (LITA = left internal thoracic artery; OM = obtuse marginal; PL = posterolateral.)

5. Fig 4
Stenosis of a Y composite graft. Three patients underwent balloon angioplasty, which was performed successfully in the stenosis of the left internal thoracic artery (LITA) just proximal to the connection of the Y composite graft. (RA = radial artery.)

6. Fig 5
Stenosis of an I composite graft. Coronary stenting was performed in the stenosis of the right internal thoracic artery (RITA) just proximal to the connection of an I composite graft in 1 patient. (RA = radial artery.)
