TCT-1 Clinical Outcomes of Robotic-Assisted Coronary Artery Bypass Grafting

In this study, we analyzed single-surgeon experience in robotic-assisted CABG. Methods All consecutive 2,280 patients undergoing robotic-assisted CABG from May 2005 to July 2021 were included. The cohort was divided into 3 subgroups of 5 years each (group A = 2005-2010; B = 2011-2016; C = 2017-2021). A propensity-adjusted matching was used for the analysis which adjusted during the modeling process (including follow-up). All patients had at least 1 follow-up. Results We included 615, 904, and 761 patients in each group. Mean ages were 65.4, 65.8, and 68.1 years old, respectively. Mean STS-PROM values were 0.9%, 0.8%, and 0.9%, respectively. Intraoperatively, 54.5%, 47%, and 39% (P < 0.0001) of patients had multiarterial CABG. Conversion to sternotomy rates decreased from 1.8% to 1.7% to 1.5% (P = 0.49), respectively. Mean OR time (hours) decreased (6.4 vs 6.2 vs 5.5) (P < 0.0001) in the 3 periods. Postoperatively, prolonged ventilation time >24 hours (P = 0.03), AKI (P = 0.002), and platelet transfusion units (P = 0.002) significantly decreased from the first to the second to the last period. Thirty-day mortality was 1.5%, vs 1%, vs 0.9% (P = 0.586) in each period. In addition, overall (all 3 groups) repeated intervention on target vessel with PCI was 0.3%. At follow-up, all-cause death (P < 0.0001), MACCE (P < 0.0002), stroke (P < 0.0001), and MI (P = 0.04), decreased from the first to the last period. Repeated revascularization with stents decreased from 99/606 (16.3%) to 143/895 (16%) to 74/754 (9.8%) (P < 0.0001), respectively
