BackgroundThis study aims to compare the characteristics between patients who underwent aortic valve replacement (AVR) through a J-shaped upper mini-sternotomy (UMS) and patients who underwent full sternotomy (FS) in the basis of clinical care and hospital outcomes.MethodsA retrospective, cross-sectional study was conducted on adult patients who were subjected to AVR by UMS from 2014 to 2017, compared with a historical control of patients who had undergone UMS by FS from 2011 to 2014. Patients, who received combined valve replacement or aortic surgery, as well as heart valve reinterventions due to endocarditis, were excluded. Sociodemographic characteristics, medical history, hospital and intensive care stay, blood transfusions, complications, and mortality of both procedures were compared.ResultsThere were 57 patients under UMS and 99 patients under FS included in this study. The median age was 67 years, and 56.77% of the patients were male. No differences were observed in the past medical history and the type of valve implanted between the groups. During surgery, patients under UMS received a lower percentage of red blood cell and platelet transfusions compared with FS. However, UMS had a higher percentage of cryoprecipitate transfusion. Intensive care stay was shorter in UMS compared with FS (three days; interquartile range [IQR], 2-4; and four days; IQR, 2-6, respectively) without differences in overall hospital stay, postoperative complications, in-hospital mortality, and 30-day mortality.ConclusionsThe J-shaped upper mini-sternotomy is a feasible surgical technique that does not increase in-hospital or 30-day mortality, neither hospital stay nor infectious complications.
