Background: The choice between a mechanical or bioprosthetic valve replacement device is
not always clear, although patient age is most often the determining factor. We reviewed our …

A total of 1689 consecutive patients underwent isolated aortic valve replacement at the
Cleveland Clinic Foundation from 1972 through 1986. There were 57 (3.4%) in-hospital …

Objective: The purpose of this study was to optimize selection criteria of biologic versus
mechanical valve prostheses for aortic valve replacement. Methods: Retrospective analysis …

OBJECTIVES: Recent evidence indicated that the use of a bioprosthesis in young patients at
first-time aortic valve replacement (AVR) is associated with an increased reoperation risk …

OBJECTIVES The goal of this study was to compare long-term survival and valve-related
complications between bioprosthetic and mechanical heart valves. BACKGROUND Different …

Mechanical valves used for aortic valve replacement (AVR) continue to be associated with
bleeding risks because of anticoagulation therapy, while bioprosthetic valves are at risk of …

Background. Concomitant coronary artery disease with aortic valve disease is an
established risk factor for diminished late survival. This study evaluated the results of …

Aims The objective was to investigate the long-term all-cause mortality in patients aged 50–
69 years after aortic valve replacement (AVR) with bioprosthetic or mechanical valves …

The main purpose of this meta-analysis was to compare the outcomes of patients who
randomly received mechanical valves or bioprosthesis, over a long-term clinical follow-up …

Objectives Improved durability and preference to avoid anticoagulation have led to
increasing use of bioprostheses in younger patients despite the need for eventual …
