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 ...

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 ...

Third Re-Do Surgery in a Young Woman with Massive Early Double-Valve Prosthesis and Thromboembolic Stroke [PDF]

Romanian Journal of Cardiology, 2021
Valvular heart disease affects more that 100 million people worldwide. Valvular replacement remains the only definite treatment for most of the patients with severe disease. Careful medical management and periodic follow up of valve function is mandatory

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.

How rare is isolated rheumatic tricuspid valve disease? [PDF]

, 2020
The incidence of rheumatic fever (RF) has markedly decreased in Europe since the beginning of the 20th century due to improved living conditions, early antibiotic therapy in streptococcal pharyngitis, and changes in serotypes of circulating streptococci.

Heyde Syndrome Treated by Conventional Aortic Valve Replacement [PDF]

Brazilian Journal of Cardiovascular Surgery, 2019
Heyde syndrome manifests as aortic stenosis associated with gastrointestinal bleeding. We describe the case of a 64-year-old man who came to the emergency room due to acute heart failure and intermittent gastrointestinal bleeding.
