ABSTRACT Introduction: Minimally invasive methods have become more preferred in cardiac surgery today. In this study, the comparative results of patients who underwent an aortic root, arch or hemiarch replacement by ministernotomy and full sternotomy in our clinic are presented. Methods: Between January 2017 and October 2019, a series of operations including aortic root, ascending aorta, and aortic arch replacements were performed on 278 patients. The ministernotomy technique was used in 25 of them. Twenty patients who underwent full sternotomy were selected and matched to this group for comparison. Results: The ministernotomy group had a longer cross-clamping time (128.3±30.8 vs. 104.7±23.4 min, P=0.007) but the total operating time was similar in the two groups (249.76±28.56 vs. 248.25±37.53 min, P=0.879). The number of red blood cell (RBC) transfusions per patient was higher in the full sternotomy group (4.65±3.74 vs. 2.44±1.85 unit, P=0.020). The ministernotomy group had shorter ventilation times (7.60±4.88 vs. 32.30±32.25 h, P<0.001) and shorter ICU stay (1.56±0.58 vs. 3.35±1.46 d, P<0.001). The 30-day mortality was 0% in the ministernotomy group. Conclusion: Early results of our study show that, in combined or isolated aortic root, ascending aorta, and aortic arch surgeries, ministernotomy can be applied with relatively safety and low mortality and morbidity rates.
