OBJECTIVE: The mini-sternotomy approach is becoming a widespread technique for aortic valve surgery. However, its safety for aortic root replacement has yet to be established. The aim of the present study was to compare the operative outcomes of patients who underwent aortic root replacement via upper mini-sternotomy (mini-Bentall) to patients who underwent Bentall procedure via median sternotomy (full-sternotomy Bentall). METHODS: Between November 1998 and November 2016, 91 consecutive patients underwent full-sternotomy Bentall procedure and 26 patients underwent mini-Bentall procedure. The mini-Bentall procedure was performed via an upper hemisternotomy incision extending to the right fourth intercostal space. Patients with concomitant procedures and those who underwent deep hypothermic circulatory arrest were excluded from the analysis. Outcome variables were operative mortality and major surgical complications, including prolonged length of hospital stay, transfusion rates, reoperation for bleeding, and prolonged ventilatory support. RESULTS: No significant differences were observed on the preoperative, operative, and postoperative characteristics between the two treatment groups. The median cardiopulmonary bypass and aortic cross-clamp times were 169 minutes (interquartile range = 156.0-188.5) and 148 minutes (interquartile range = 131.3-160.3) in the mini-Bentall group, respectively. The median duration of hospitalization in the mini-Bentall group was 6.5 days (interquartile range = 5.0-11.0 days). In-hospital mortality and new renal insufficiency occurred at a frequency of 1.1% and reoperation for bleeding at 6.6% in the group of patients who underwent the conventional Bentall procedure compared with 0% for all these measures in the mini-Bentall group (P > 0.33). There was no significant difference in intraoperative red blood cell transfusion and other major postoperative complications. No strokes were observed in either group, and there were no conversions to median sternotomy in the mini-Bentall group. CONCLUSIONS: An upper hemisternotomy is a feasible technique in patients undergoing elective aortic root replacement surgery. However, future prospective studies are required before these procedures become the standard of care.
