Influence of moderate prosthesis–patient mismatch on long-term outcomes in patients with severe aortic stenosis with paradoxically reduced gradients against the background of reduced stroke volume after aortic valve replacement with a biological prosthesis: retrospective comparative study [PDF]
КардиоСоматика, 2023 OBJECTIVE: Our aim was to evaluate the impact of moderate prosthesis–patient mismatch on long-term results after aortic valve replacement in patients with severe aortic stenosis with paradoxically reduced gradients against the background of a reduced ...

Two-dimensional finite element simulation of fracture and fatigue behaviours of alumina microstructures for hip prosthesis [PDF]
Proceedings of the Institution of Mechanical Engineers, Part H:
Journal of Engineering in Medicine 225, 12 (2011) 1158-1168, 2012 This paper describes a two-dimensional (2D) finite element simulation for fracture and fatigue behaviours of pure alumina microstructures such as those found at hip prostheses. Finite element models are developed using actual Al2O3 microstructures and a bilinear cohesive zone law. Simulation conditions are similar to those found at a slip zone in a dry

An echocardiographic comparison of sutureless and conventional aortic valve replacement : a matched case-control study [PDF]
, 2018 Background: Patients at a high operative risk for conventional aortic valve replacement (AVR) may be offered sutureless valve implantation. Sutureless valves resemble conventional valves but incorporate an anchoring mechanism without using annular ...

A critical comparison of methods for the determination of the ageing sensitivity in biomedical grade yttria stabilized zirconia [PDF]
Journal of Biomedical Materials Research 72(2), 239-245 (2005), 2017 Since the recent failure events of two particular series of zirconia femoral heads for total hip replacement prosthesis, a large decrease in the use of zirconia ceramics for orthopaedic implants has been observed. In spite of the biomedical success of this material during the last ten years, this was required for safety reasons, until the cause of the ...

Disassembly and Dislocation of a Bipolar Hip Prosthesis
Journal of the Formosan Medical Association, 2008 Dislocation of a hip prosthesis is a common complication. In usual cases of hip prosthesis dislocation, the prosthetic femoral head comes out from either the natural acetabular cavity in a bipolar hemiarthroplasty or the prosthetic acetabulum in a total ...

Fixed Prosthesis Failures: Survey among Moroccan Dentists
Scholars Journal of Dental Sciences, 2023 Introduction: The fixed prosthesis reveals many prosthetic complications, which occur most often by not respecting the appropriate means of approach. This error concerns both the clinic and the laboratory additionally it may be due to simply not knowing ...
