OBJECTIVE: The advantage of robotically assisted minimally invasive approach for single vessel disease has been well documented and widely accepted for its easiness of harvesting internal mammary artery and reliable mid-term graft patency. However, the application of this advantage to multi-vessel revascualrization through minimally invasive approach has not been fully investigated. We retrospectively reviewed our early experience with robotically assisted IMA harvesting and off-pump multi-vessel revascuarizaiton through minimally invasive approach with LIMA/RIMA-SVG composite graft . METHODS: From August 2018 to December 2019, 31 patients(22 male and 9 female, average age 61±10 years, 35.5% with diabetes) underwent robotically assisted IMA harvesting (LIMA/BIMA) and multi-vessel revascuarizaiton through 8-10cm left thoracotomy minimally invasive approach with LIMA/RIMA-SVG composite graft (Y or I-composite graft). Perioperative outcomes were analyzed. RESULTS: Among the 31 patients, robotically BIMA harvesting was used in 17 (54.8%) patients including 10 patients with a RIMA-SVG composite "I" grafts. LIMA-SVG/RIMA composite "Y" graft was used in 15 patients(48.4%). An average of 2.3±0.5 grafts were used in the operations. Double, triple, and quadruple MICSCABG was performed in 24(77.4%),6(19.4%), and one(3.2%) patients, respectively. There was no hospital mortality or conversion to conventional CABG and all the LIMA or BIMA were harvested uneventfully with good blood flow (21.2±11.5ml/min). The blood loss during surgery was 129±147ml. One post-operative death (3.2%) due to infection and one case of TIA (3.2%) was noted. All other patients (93.5%) were discharged uneventfully and remained well to this day. CONCLUSIONS: Robotically assisted LIMA/BIMA harvesting and off-pump multivessel revascuarizaion through minimally invasive approach is safe and feasible. With LIMA/RIMA-SVG"Y"or "I" composite graft, the advantage of robotic system in havesting IMA was fully utilized and the challenge of completing the proximal anastomosis was resolved with a real "no-touch" technique. Long-term follow-up is warranted to investigate the graft patency and clinical result.
