Introduction: We aim to analyze long-term repeat intervention incidence in octogenarians undergoing robotic-assisted coronary artery bypass grafting (CABG).

Hypothesis: We hypothesize that robotic-assisted CABG has a low incidence of repeat intervention compared to other clinical trials.

Methods: All consecutive octogenarians (500 patients) undergoing robotic-assisted left internal thoracic artery (LITA) harvesting and CABG through a 4-cm left minithoracotomy with LITA to left anterior descending (LAD) artery anastomosis between 2005-2021 in a single center were included. Hybrid coronary revascularization (HCR) consists in robotic-assisted CABG followed by percutaneous coronary intervention (PCI) with DES in a non-LAD target within 7-days from the operation.

Results: Preoperatively, mean age was 83 (±2.9) year-olds, and mean STS-PROM risk score was 3.6% (2.1- 6.6). Intraoperatively, 478 (95.6%) patients received 1 LITA, 14 (12.8%) received bilateral ITA, and 8 (1.6%) a saphenous venous graft. A total of 303 (60.6%) patients received multiple arterial revascularizations while 140 (28%) received HCR. A total of 376 (75.2%) patients were extubated in the operating room. Postoperatively, 2 (0.4%) patients experienced non-fatal stroke, 6 (1.2%) had reoperation for bleeding, and 12 (2.4%) had renal failure. There was no 30-day mortality while 1 (0.2%) patient had PCI with DES on LITA-LAD anastomosis due to graft failure. Mean-follow-up was 2.9-years while incidence of all-cause death was 103 (20.6%) patients, MACCE 136 (27.2%), stroke 8 (1.6%), myocardial infarction 16 (3.2%), and repeat intervention with stents 39 (7.8%) were low. There was no repeat surgical intervention while PCI with drug-eluting stents for new coronary disease was 15/39 (38.4%) patients.

Conclusions: Robotic-assisted CABG in octogenarians evidenced a 7.8% incidence of repeat intervention with stents.
