Description
Summary:The right internal mammary artery is considered to be the second choice for arterial conduits for coronary artery bypass grafting (CABG). However, the widespread use of bilateral internal mammary artery (BIMA) grafting is limited owing to increased technical demands, lengthy procedure, and high incidence of sternal wound complications. We compared the early clinical outcomes of a novel robot-assisted double-docking technique (DDT) with an open sternotomy technique for total arterial revascularization using BIMA. Between June 2019 and June 2023, 445 patients with multivessel coronary artery disease underwent open sternotomy CABG using BIMA grafting and 145 patients underwent robot-assisted BIMA grafting using DDT. Comparative analysis of 104 pairs of matched patients obtained using propensity score matching was performed. Procedural characteristics, postoperative 30-day mortality, and composite outcome (major adverse cardiac and cerebrovascular events) at a median follow-up of 1.5 years were evaluated. Preprocedural characteristics were well balanced between the groups after propensity matching. The number of distal anastomoses performed in the conventional group was statistically higher than that performed using DDT ( < 0.001). The durations of postsurgical ventilation, intensive care unit stay, and in-hospital stay were significantly lower with the DDT than with conventional CABG ( < 0.001). There was no significant difference in all-cause mortality or major adverse cardiac events between the DDT and conventional CABG groups at a median follow-up of 1.5 years. The DDT is feasible and efficacious for revascularization of multiple coronary targets in select individuals. It is equivalent to open sternotomy in terms of early clinical outcomes and superior to open sternotomy with regard to rates of sternal infection and intensive care unit and in-hospital stay.
