To compare outcomes of three methods of coronary artery bypass graft surgery (CABG): robotic off-pump hybrid coronary revascularization (HCR) versus conventional CABG off-pump (off-pump coronary artery bypass [OPCAB]) and on-pump (on-pump coronary artery bypass [ONCAB]) in women.Data on women who underwent robotic off-pump HCR or conventional OPCAB or conventional ONCAB between May 2005 and January 2021 were collected. Inverse probability of treatment weighting (IPTW) with doubly robust method was used to analyze the data.A total of 731 women were included (181 robotic off-pump HCR, 138 conventional ONCAB, and 412 conventional OPCAB cases). IPTW-adjusted analyses revealed the following: (1) for operative times, robotic off-pump HCR presented longer times when compared with OPCAB, but shorter times when compared with ONCAB; (2) compared with ONCAB and OPCAB, robotic off-pump HCR presented lower rates of reintervention for bleeding, intra- and postoperative blood transfusions, higher rates of extubation in the OR with less prolonged ventilation, lower rates of postoperative atrial fibrillation, and shorter intensive care unit and hospital length of stay; (3) no statistically significant differences for operative mortality were observed comparing robotic off-pump HCR with ONCAB (IPTW-adjusted odds ratio [OR]: 0.77; 95% confidence interval [CI]: 0.07-7.85; p = .822) and with OPCAB (IPTW-adjusted OR: 4.27; 95% CI: 0.27-66.88; p = .301); 4. long-term survival was similar with HCR compared with ONCAB (hazard ratio [HR]: 0.74, 95% CI: 0.36-1.50, p = .401) and OPCAB (HR: 0.89, 95% CI: 0.50-1.58, p = .683).In our local experience, robotic off-pump HCR in women was as safe as conventional ONCAB and OPCAB and may further improve postoperative outcomes when performed frequently by a dedicated team, producing better perioperative outcomes without compromising survival in the long run.
