FIGURE 1 Kaplan-Meier curve of long-term survival
As listed in Table 7, the predictors of long-term mortality were DM
(p=0.003), gastrointestinal disease (p=0.03) and CreatCl (p=0.001) as a
predictor of long-term survival, on univariable analysis.
On multivariable analysis, DM (HR 2.78 CI95: 1.15-6.72; p=0.023)
increased the risk of follow-up mortality and CreatCl (HR 0.98 CI95:
0.95-0.99; p=0.013) was associated with a lower risk of follow-up
mortality.
Three patients (3.5%) required late reoperation. The causes for
reoperation were prosthesis/repair malfunction (2.3%) or endocarditis
(1.2%).
