Key result
The valve-in-valve technique for degenerated mitral bioprostheses raises methodological and clinical concerns regarding historical bias, endocarditis risk, and suboptimal hemodynamic performance.
Why the study?
Does the valve-in-valve or valve-over-valve technique reduce early mortality and late prosthetic valve dysfunction compared to explantation in patients with degenerated mitral bioprostheses?

A Mazzucco (1997) conducted a letter in Degenerated mitral bioprostheses. Valve-in-valve or valve-over-valve technique vs. Explantation technique was evaluated. The valve-in-valve technique for degenerated mitral bioprostheses raises methodological and clinical concerns regarding historical bias, endocarditis risk, and suboptimal hemodynamic performance.
