This study was retrospective observational study, employing regressions, and bivariate correlations in the statistical analysis. A total of 114 patients over 65 years of age referred to cardiac surgery: 57 subjects in the minimum access group and 57 subjects in the sternotomy group. The main variables of interest were: demographic variables, PO course, mainly mortality, as well as duration of admission to critical care and total admission time. The mean age was 73.11 years, with 52.6% of women and 47.4% of men, and no significant differences between the pre-operative characteristics of either group. Regarding mortality, this was lower in the minimum access group, statistically significant in the analysis using bivariate correlations. Aortic valve replacement using a minimally invasive approach is a safe technique in our environment, despite its necessary learning curve.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Cirugía convencionalCirugía mínimamente invasivaConventional surgeryMinimum access surgeryMortalidadMortalityResultadosResultsAgedAortic ValveFemaleHeart Valve Prosthesis ImplantationHumansMaleMinimally Invasive Surgical ProceduresSternotomyTreatment Outcomeresearch article35636934open access10.24875/CIRU.210002952444-054Xhttps://www.cirugiaycirujanos.com/files/circir_22_90_3_303-309.pdf
