Transcatheter mitral valve replacement versus redo surgery for mitral prosthesis failure: A systematic review and meta-analysis [PDF]

Frontiers in Cardiovascular Medicine, 2023
BackgroundTranscatheter mitral valve replacement (TMVR) has emerged as an alternative to redo surgery. TMVR compared with redo surgical mitral valve replacement (SMVR) in patients with mitral prosthesis failure remains limited.

Early stenotic prosthesis failure after implantation of a stentless porcine aortic valve prosthesis [PDF]

Interactive Cardiovascular and Thoracic Surgery, 2011
Stentless biological aortic prostheses are used routinely in aortic valve replacement surgery, offering beneficial hemodynamics compared to stented biological valves of similar size. We report here a rare case of early stenotic prosthesis failure of a RootElan stentless porcine aortic valve prosthesis due to swelling at the bottom of the right coronary

Autoinflation Leading to Failure of Two-Piece Ambicor Implantable Penile Prosthesis: An Outcome from a Methodical Treatment of Recalcitrant Stuttering Priapism

Case Reports in Urology, 2014
Introduction. We present the case of a patient who received a two-piece Ambicor penile prosthesis for idiopathic recurrent “stuttering” priapism refractory to other treatment options.

Biomechanical study of screw-supported prosthesis in acetabular revision [PDF]

Bone & Joint Research
Aims: Acetabular bone defects pose a common challenge in revision total hip arthroplasty (THA). Our team has applied screw-supported prostheses to the revision of severe acetabular defects and achieved good early clinical results.

Catastrophic failure of a monolithic zirconia prosthesis

The Journal of Prosthetic Dentistry, 2015
Recently, monolithic zirconia restorations have received attention as an alternative to zirconia veneered with feldspathic porcelain to eliminate chipping failures of veneer ceramics. In this clinical report, a patient with mandibular edentulism received 4 dental implants in the interforaminal area, and a screw-retained monolithic zirconia prosthesis ...

Failure analysis of a Ti6Al4V cementless HIP prosthesis

Engineering Failure Analysis, 2007
This work investigates the causes of in vivo fracture of a cementless hip prosthesis model manufactured with Ti6A14V alloy. To this end an assessment of geometric characteristics, a fractographic analysis of the fracture surface, and a microstructural study of the stem material were carried out.

Combining deep learning and machine learning for the automatic identification of hip prosthesis failure: Development, validation and explainability analysis

Int. J. Medical Informatics, 2023
AIM Revision hip arthroplasty has a less favorable outcome than primary total hip arthroplasty and an understanding of the timing of total hip arthroplasty failure may be helpful.

Minimizing Risk of Failure from Ceramic-on-Ceramic Total Hip Prosthesis by Selecting Ceramic Materials Based on Tresca Stress

Sustainability, 2022
The choice of ceramic-on-ceramic coupling in total hip prosthesis has advantages over couplings with other combinations of materials that use polyethylene and metal materials in terms of high hardness, scratch resistance, low wear rate, and increased ...
