Mid-Term Outcome of Mechanical Pulmonary Valve Prostheses: TheImportance of Anticoagulation [PDF]
Journal of Cardiovascular and Thoracic Research, 2014 Introduction: Pulmonary valve replacement (PVR) is being performed more commonly lateafter the correction of tetralogy of Fallot. Most valves are replaced with an allograft or xenograft,although reoperations are a common theme. Mechanical prostheses have

Mechanical evaluation of the “Hüfner hand” prosthesis
Prosthetics & Orthotics International, 2020 Background: Current body-powered hands have very low acceptance rates. They also require high activation forces. In the past, a high acceptance rate was reported for the then-available Hüfner hand, a hand which could be controlled by relatively low activation forces.

How should we assess the mechanical properties of lower-limb prosthesis technology used in elite sport?: An initial investigation [PDF]
, 2013 Despite recent controversy, it is not yet formally recognised how lower-limb prosthesis should be assessed for their performance. To assist in this process, experiments are undertaken to investigate the linearity, stiffness and assessment of feet based ...

Leaflet migration in an aortic bileaflet mechanical prosthesis [PDF]
European Heart Journal, 2015 A 41-year-old man was referred to the emergency department for transient atypical chest pain. Six years before presentation, he underwent concomitant aortic and mitral mechanical valve replacement for a bicuspid aortic valve regurgitation and a regurgitating mitral valve prolapse. A significant paravalvular leak of the 21 mm …

Replacement of aortic valve flaps with an autopericardium using the S. Ozaki technique
Вестник хирургии имени И.И. Грекова, 2023 Classical aortic valve replacement is often fraught with negative outcomes for patients. When replacing the aortic valve with a mechanical valve prosthesis, the patient is associated for life with the use of indirect anticoagulants, which often leads to ...
