The structural-geometric and functional parameters of the heart in patients after mitral prosthetics with new full-flow valves in the long-term period [PDF]

КардиоСоматика, 2022
Aim. To compare the results of mitral valve replacement with the full-flow mechanical valve MedInzh-ST and the classical prosthesis MedInzh-2, to learn the structural and functional parameters of the heart depending from the prosthesis in the long-tern ...

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 ...

Developing the Tissue Engineered Heart Valve – a Descriptive Hemodynamic and Ultrasound in Vitro Characterization Study of Heart Valves in a Bioreactor [PDF]

Romanian Journal of Cardiology, 2021
The inherent limitations of current heart valve substitutes create the premise for the Tissue Engineered Heart Valve (TEHV), considered the perfect substitute. We aimed to compare in vitro hemodynamic performances of our TEHV, the conventional prosthetic

Dynamic Echocardiographic Imaging of a Valve-in-Valve Mitral Prosthesis

Case Reports in Radiology, 2022
Dynamic imaging of heart valves and specifically prosthetic valves is a central benefit of echocardiography. Most bioprosthetic heart valves degenerate over a given time and hence require repeat valve replacement which carries a significant risk of ...

A rare case series of mechanical prosthetic heart valve structural deterioration presented as severe mitral regurgitation

Heart Vessels and Transplantation, 2023
Objective: Structural valve deterioration in the form of stenosis or regurgitation or both though being a rare complication with newer generation mechanical heart valves can occur and can be critical.

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.

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.
