Postoperative outcomes
Postoperative outcomes are summarized in Table 3. Operative mortality
was 9.4% among males and 13.8% among females, though this was not a
statistically significant difference (p=0.098). Males had a
significantly higher rate of ≥ moderate residual aortic insufficiency
and lower 1-month follow-up ejection fraction than females. Females had
a longer duration of postoperative mechanical ventilation than males
did. Rates of pneumonia, stroke, new-onset renal failure requiring
dialysis, and re-exploration for bleeding were comparable between
groups. Postoperative length of stay was also comparable between groups.
