[MIDCAB for redo patients using the LITA-RA composite graft]

Redo coronary artery bypass grafting (CABG) is associated with higher mortality, low-output syndrome, perioperative myocardial infarction than primary CABG. Minimally invasive direct coronary artery bypass grafting (MIDCAB) technique avoids the manipulation of old graft and injury of the adhesive heart in redo operation. We performed the MIDCAB procedure for 2 redo cases using the left internal thoracic artery (LITA)-radial artery (RA) composite graft. The LITA-RA composite graft was anastomosed to the left anterior descending branch (LAD) through small left anterior thoracotomy without cardiopulmonary bypass. Postoperative coronary artery graphy shows the widely patent of new graft. The MIDCAB procedure using the LITA-RA composite graft is safe and useful to regulate the bypass graft length and avoid the widely harvest of LITA in redo operation.
