Peri-operative Outcomes and Post-MVR Survival
Secondary outcomes for these patients after propensity matching are
summarized in tables 5 and 6. There were no significant differences in
mortality during the at 30 days, 1 year, or at longest follow-up.
Although at all time points after 1 year, males had a numerically higher
mortality rate than females (figure 2, table 5). At the median follow up
time of 8.4 years, there were 107 deaths in the male group (57.5%) and
99 deaths in the female group (50.9%) [adjusted hazard ratio (HR):
1.19; 95% confidence interval (CI): 0.9-1.56; p=0.22]. Males were
more likely to experience an MI during the follow-up period with 20 MIs
recorded (8.9%) and 10 MIs recorded for the female group (5.5%) [HR:
2.16; 95% CI: 1.02-4.59; p=0.045]. Males were also more likely to
develop sepsis postoperatively. 28 males (8.9%) and 11 females (3.5%)
developed sepsis postoperatively (p=0.005). There were no significant
differences in the incidence of heart failure, readmission for stroke,
reoperation of the MV, residual MR, new-onset AF, pacemaker insertion
rates, or acute kidney injury postoperatively.
