Reoperative surgery for degenerated aortic bioprostheses: predictors for emergency surgery and reoperative mortality
Key result
Emergency reoperation for degenerated aortic bioprostheses was associated with significantly higher operative mortality compared to elective replacement (22.6% vs 1.4%; P<0.0001).

Does emergency reoperation compared to elective reoperation increase operative mortality in patients with degenerated aortic bioprostheses?

Overview
Supports early detection of bioprosthetic failure to enable elective reoperation; leaves open prospective validation of timing strategies.

Main Result
Odds Ratio: 11.17 (95% CI 4.33–28.85)
Absolute Event Rate: 22.6% vs 1.4%
p-value: p=<0.0001
Elective replacement of failed aortic bioprostheses is safe with low mortality (1.4%), whereas emergency reoperation carries a significantly higher mortality risk (22.6%), emphasizing the need for early intervention at the first sign of dysfunction.
Cite This Study
Vogt et al. (2000) conducted a cohort in Degenerated aortic bioprostheses (n=172). Emergency reoperation vs. Elective replacement was evaluated on Operative mortality (OR 11.17, 95% CI 4.33-28.85, p=<0.0001). Emergency reoperation for degenerated aortic bioprostheses was associated with significantly higher operative mortality compared to elective replacement (22.6% vs 1.4%; P<0.0001).
