Natural Polymers in Heart Valve Tissue Engineering: Strategies, Advances and Challenges

open access: yesBiomedicines, 2022
In the history of biomedicine and biomedical devices, heart valve manufacturing techniques have undergone a spectacular evolution. However, important limitations in the development and use of these devices are known and heart valve tissue engineering has

Which Biological Properties of Heart Valves Are Relevant to Tissue Engineering?

open access: yesFrontiers in Cardiovascular Medicine, 2020
Over the last 20 years, the designs of tissue engineered heart valves have evolved considerably. An initial focus on replicating the mechanical and structural features of semilunar valves has expanded to endeavors to mimic the biological behavior of ...

FLUID MECHANICS OF ARTIFICIAL HEART VALVES [PDF]

open access: yesClinical and Experimental Pharmacology and Physiology, 2009
SUMMARY Artificial heart valves have been in use for over five decades to replace diseased heart valves. Since the first heart valve replacement performed with a caged‐ball valve, more than 50 valve designs have been developed, differing principally in valve geometry, number of leaflets and material.

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

open access: yesCase 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 ...

Midterm outcomes of mechanical versus bioprosthetic valve replacement in middle-aged patients: An Indian scenario

open access: yesHeart India, 2017
Objective: The goal of this study is to evaluate and compare the midterm outcomes of bioprosthetic heart valve replacement in terms of survival, valve-related events, quality of life, and economic aspects of treatment in population age 45 years and above

Mechanical Heart Valves in Pregnancy [PDF]

open access: yesCirculation, 2015
Caring for women with mechanical heart valves (MHVs) in pregnancy poses one of the greatest clinical challenges in our specialty. Pregnancy is a prothrombotic state because of the relative increases in fibrinogen, plasminogen activator inhibitors, clotting factors, Von Willebrand factor, and platelet adhesion molecules, and concomitant decreases in ...

Mechanical Heart Valves [PDF]

open access: yesCirculation, 2007
The report by Svennevig and colleagues in this issue of Circulation will stand as an important contribution to our knowledge of the outcomes after heart valve replacement.1 This article, along with other extensive published series of patients followed up for as many as 4 decades after mechanical heart valve replacement, now help form the basis on which

Transient Study of Flow and Cavitation Inside a Bileaflet Mechanical Heart Valve

open access: yesApplied Sciences, 2020
A mechanical heart valve (MHV) is an effective device to cure heart disease, which has the advantage of long life and high reliability. Due to the hemodynamic characteristics of blood, mechanical heart valves can lead to potential complications such as ...

Replacement of aortic valve flaps with an autopericardium using the S. Ozaki technique

open access: yesВестник 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 ...
