Abstract OBJECTIVES: There are few reports on the outcome of total arch replacement (TAR) with concomitant coronary artery bypass grafting (CABG); the present study was aimed at analysing outcomes after TAR with CABG at our institute. METHODS: Between January 2002 and December 2012, 123 consecutive patients underwent elective TAR with or without CABG. The patients were divided into two groups: 46 who had concomitant CABG (Group T/C) and the rest, who had TAR only (Group T). TAR was performed under mild hypothermic circulatory arrest and selective antegrade cerebral perfusion (SACP) using a four-branched arch graft. RESULTS: The number with a low ejection fraction (<50\%) was higher in Group T/C, in which the additive and the logistic EuroSCORE were also higher. The mean number of coronary anastomoses was 1.6 ± 0.8 in Group T/C. The mean durations of surgery (P < 0.01), cardiopulmonary bypass (P < 0.01), cardiac ischaemia (P < 0.01) and SACP (P < 0.01) were significantly longer in Group T/C. The early graft patency of bypass grafts was 96.7\%. Between Group T and Group T/C, there were no significant differences in the incidence of stroke (3.9 and 10.9\%, P = 0.13), perioperative myocardial infarction (0 and 2.2\%, P = 0.37) and in-hospital mortality (2.6 and 8.7\%, P = 0.14). There was one case of 30-day mortality in each group. Preoperative haemodialysis, NYHA III/IV and operation time were multivariate predictors (P < 0.05) of in-hospital mortality. CONCLUSIONS: Although concomitant CABG in TAR patients had higher operative risk, it can be safely performed with favourable outcomes. © The Author 2014.
