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%).
