Key result
Operative mortality during first reoperation for bioprosthetic failure was significantly higher in patients with NYHA Class IV, lower left ventricular function, prosthetic infection, or emergency surgery.

High-risk features warrant preoperative risk stratification and optimization; leaves open whether earlier elective reoperation improves survival in bioprosthetic valve failure.
Observational (n=330)
Operative mortality for bioprosthetic valve reoperation is higher in patients with advanced heart failure symptoms, poor LV function, endocarditis, or emergency surgery, suggesting earlier intervention may reduce risk.
Bortolotti et al. (1991) conducted an observational in Bioprosthetic valve failure (n=330). First reoperation for bioprosthetic failure was evaluated on Operative mortality. Operative mortality during first reoperation for bioprosthetic failure was significantly higher in patients with NYHA Class IV, lower left ventricular function, prosthetic infection, or emergency surgery.
