Aim:

The aim of this study was to analyze the results of minimum access surgery in comparison with conventional surgery, especially in relation to post-operative (PO) mortality.

Materials and methods:

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.

Results:

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.

Conclusions:

Aortic valve replacement using a minimally invasive approach is a safe technique in our environment, despite its necessary learning curve.
