PURPOSE: We evaluated the feasibility of off-pump minimally invasive direct coronary artery bypass (MIDCAB) in combination with robotic harvesting of the left internal mammary artery (LIMA).
METHODS: Since 2004, 33 patients [average age, 64 years; 27 males (82%)] have undergone MIDCAB with robotic LIMA harvesting performed through the fourth or fifth intercostal space with guidance by enhanced computed tomography (CT).
RESULTS: No deaths or major adverse cardiac events occurred. Robotic LIMA harvesting was completed in 30 cases (91%), while three cases (9%) required conversion to a median sternotomy due to bleeding. The risk of LIMA injury significantly increased with age (p = 0.0012). For the 30 successful cases, the average harvest time was 68 min, and the average intraoperative blood loss was 306 ml, with only three patients (9%) requiring a transfusion. The graft flow was measurable in all cases (average, 34 ml/minute). All grafts were shown to be patent in postoperative evaluations, although CT revealed that the LIMA in one patient was anastomosed to an untargeted artery.
CONCLUSIONS: Off-pump MIDCAB in combination with robotic harvesting of the LIMA is a reasonable and less invasive procedure than the standard procedures. Potential problems include difficulty controlling bleeding from the graft, especially in elderly patients, and proper identification of the target artery.
