Aortic valve replacement in sheep with a novel trileaflet mechanical heart valve prosthesis without anticoagulationCentral MessagePerspective [PDF]
JTCVS Open, 2021 Background: Even after decades of intensive research, an ideal heart valve prosthesis remains elusive. Shortcomings of conventional devices include reduced durability of bioprostheses and the thrombogenicity of mechanical substitutes, necessitating ...

A Novel Sensorized Heart Valve Prosthesis: Preliminary In Vitro Evaluation. [PDF]
Sensors (Basel), 2018 Background: Recent studies have shown that subclinical valve thrombosis in heart valve prosthesis (HVP) can be responsible for reduced leaflet motion detectable only by advanced imaging diagnostics.

South African Family Practice, 2018 Background: Available evidence suggest that the optimum prothrombin time-international normalised ratio (PT-INR) intensities recommended for anticoagulation of patients with mechanical heart valve prosthesis may not apply to all race groups.

Choice of heart valve prosthesis [PDF]
Heart, 2002 It is 40 years since Starr and Edwards' description of successful prosthetic valve replacement in 1961. Some patients who underwent valve replacement with the original Starr-Edwards prosthesis in the 1960s are alive to this day. The Starr-Edwards ball and cage prosthesis, albeit in modified form, is still available commercially.

Structural valve failure of TTK Chitra heart valve prosthesis. [PDF]
Indian J Thorac Cardiovasc Surg, 2023 Mechanical prosthetic valve dysfunction can be structural or non-structural. Structural valve dysfunction includes disc dislodgement, disc fracture, and strut fracture. These events in an implanted valve are rare but could pose a risk to life. TTK Chitra heart valve prosthesis (CHVP), an Indian-made single tilting disc valve, has been implanted since ...

Structural valve deterioration in the Mitroflow biological heart valve prosthesis [PDF]
European Journal of Cardio-Thoracic Surgery, 2017 Concern has been raised regarding the long-term durability of the Mitroflow biological heart valve prosthesis. Our aim was to assess the incidence of structural valve degeneration (SVD) for the Mitroflow bioprosthesis in a nationwide study in Denmark including all patients alive in Denmark who had received a Mitroflow aortic bioprosthesis since 2000 ...
