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 ...

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 ...

The First Experience of Aortic Valve Repeated Replacement Using the “Valve in Valve” Technique in a Patient With Dysfunction of a Biological Prosthesis

Неотложная медицинская помощь, 2021
Introduction. Aortic valve replacement in cardiopulmonary bypass with suture fixation of the prosthesis is the “gold standard” in cardiac surgery. Currently, the frequency of use of heart valve bioprostheses is increasing in older patients.

Raised Prosthetic Valve Gradients: What Should be the Approach?

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2019
The introduction of valve replacement surgery has dramatically improved the outcome of patients with valvular heart disease. Echocardiography plays an important role to determine the outcome of the surgery and follow up of these patients with prosthetic ...
