Fig. 1 Preoperative computed tomography image showing LITA and RITA runing just under the sternal midline and appear to be adherent to the sternum. (yellow arrows)
LITA: left internal thoracic artery RITA: right internal thoracic artery
Fig. 2 Preoperative computed tomography image showing that RITA run across the ascending aorta (arrow)
RITA: right internal thoracic artery
Fig. 3 Preoperative coronary angiography showing RITA anastomosed to LAD (A), LITA and RA were composed as Y-graft, with LITA anastomosed to Dx, and RA to PL and PD sequentially. The right ventricular branches are not adequately contrasted, which compromise the right ventricular myocardial perfusion if cardioplegia is used. (B)
Dx: diagonal branch   LAD: left anterior descending LITA: left internal thoracic artery  PD: posterior descending branch  PD: posterior descending branch  PL: posterior lateral  RA: radial artery  RITA: right internal thoracic artery
