Seven-year results with the St Jude Medical Silzone mechanical prosthesis.

Objective: The Artificial Valve Endocarditis Reduction Trial was stopped on January 21, 2000, due to a higher incidence of paraprosthetic leak in the St Jude Medical Silzone prosthesis compared with the conventional prosthesis. The Artificial Valve Endocarditis Reduction Trial investigators reported the 2-year results in 2002. This retrospective study assessed the influence on thromboembolism and paraprosthetic leak to 7 years.

Effect of prosthesis-patient mismatch on long-term survival with mitral valve replacement: assessment to 15 years.

Background: The effect of prosthesis-patient mismatch on long-term survival after mitral valve replacement (MVR) has received limited attention. This study was performed to determine the predictors of mortality after MVR and influence of prosthesis-patient mismatch on survival.

Methods: Contemporary mechanical prostheses and bioprostheses were implanted in 2,440 patients with MVR between 1982 and 2002.

Predictors of recurrence and reoperation for prosthetic valve endocarditis after valve replacement surgery for native valve endocarditis.

Objective: Surgical treatment of native valve endocarditis remains challenging, especially in cases with paravalvular destruction. Basic principles include complete debridement and reconstruction. This study is designed to evaluate the outcomes of surgical reconstruction of complex annular endocarditis using standard techniques and materials, including autologous and bovine pericardium.

Carpentier-Edwards supra-annular aortic porcine bioprosthesis: clinical performance over 20 years.

Objective: Experience with the Carpentier-Edwards supra-annular porcine bioprosthesis (Edwards Lifesciences, Irvine, Calif) has been evaluated longitudinally over 20 years. Clinical performance was evaluated by actuarial and actual analysis. Hemodynamic performance was evaluated by echocardiographic/Doppler assessment.

Medtronic mosaic porcine bioprosthesis: investigational center experience to six years.

Background And Aim Of The Study: The findings of this single-center experience with the Medtronic Mosaic porcine bioprosthesis were evaluated to determine the clinical performance of the valve.

Methods: Between 1994 and 2000, a total of 657 patients was implanted with the prosthesis. Aortic valve replacement (AVR) was performed in 415 patients (mean age 70.
