Introduction: Full sternotomy is the gold standard for aortic root surgery. However, some individuals may benefit from an upper mini-sternotomy. Objective: The aim of the present study was to match results between cases who received aortic root replacement by an upper mini-sternotomy (mini-Bentall) and those who underwent the treatment through a median sternotomy (full-sternotomy Bentall). Patients and methods: A total of 20 patients got the full-sternotomy Bentall operation and 9 patients underwent the mini-Bentall treatment between November 2016 and November 2020. Mini-Bentall surgery was accomplished by an incision beginning at the right upper sternal border and finishing at the fourth right intercostal gap. Concurrent surgeries, such as mitral valve intervention or aortic dissection, and profound hypothermic circulatory arrest, disqualified patients from participation. Major surgical complications and operative mortality were measured, as were open chest and re-exploration for bleeding, hospital length of stay, blood transfusion rates, and duration of mechanical ventilation. Results: The rate of serious postoperative problems, including the need for a blood transfusion, was not significantly different between the two groups. There were no cases of stroke in either group, and the mini-Bentall group did not have any conversions to median sternotomies. Conclusion: In certain individuals undergoing elective aortic root replacement surgery, a partial upper J-shaped sternotomy can be a secure and alternative approach. Unfortunately, further research is needed before this method can replace current best practises.
