Histological assessment of the human heart valves and its relationship with age

Anatomy & Cell Biology, 2020
The human heart valves are complex anatomical structures consisting of leaflets with many supporting structures. With advancing age, the microstructure of the components of the valves can change.

One-Year Outcomes of Mitral Valve-in-Valve Using the SAPIEN 3 Transcatheter Heart Valve.

JAMA cardiology, 2020
Importance Bioprosthetic mitral valves are implanted with increasing frequency but inevitably degenerate, leading to heart failure. Reoperation is associated with high morbidity and mortality.

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.

Differential Biological Effects of Dietary Lipids and Irradiation on the Aorta, Aortic Valve, and the Mitral Valve

Frontiers in Cardiovascular Medicine, 2022
AimsDietary cholesterol and palmitic acid are risk factors for cardiovascular diseases (CVDs) affecting the arteries and the heart valves. The ionizing radiation that is frequently used as an anticancer treatment promotes CVD.

Comparative Anatomy of Mitral and Tricuspid Valve: What Can the Interventionlist Learn From the Surgeon

Frontiers in Cardiovascular Medicine, 2018
Transcatheter valve interventions on the mitral and tricuspid valves entail increasing complexity. Part of the knowledge that has been generated during the development of mitral devices can be transferred to the tricuspid valve (TV).

Combined cesarean section and mitral valve replacement in severe symptomatic mitral valve disease with unfavorable valve anatomy: Experience at a tertiary referral center of North India

Heart India, 2019
Objective: To discuss the management in a subset of patients with severe mitral valve disease having calcified, nonpliable valves not suitable for percutaneous balloon mitral valvuloplasty during pregnancy, presenting with Stage III–IV of the clinical ...

Flow structure in healthy and pathological left ventricles with natural and prosthetic mitral valves

Journal of Fluid Mechanics, 2017
In this paper, the structure and the dynamics of the flow in the left heart ventricle are studied for different pumping efficiencies and mitral valve types (natural, biological and mechanical prosthetic).

Thirty-Day Outcomes of Transcatheter Mitral Valve Replacement for Degenerated Mitral Bioprostheses (Valve-in-Valve), Failed Surgical Rings (Valve-in-Ring), and Native Valve With Severe Mitral Annular Calcification (Valve-in-Mitral Annular Calcification) in the United States

Circulation. Cardiovascular Interventions, 2020
Background: Transcatheter mitral valve replacement using aortic transcatheter heart valves has recently become an alternative for patients with degenerated mitral bioprostheses, failed surgical repairs with annuloplasty rings or severe mitral annular ...

Collagen composition of normal and myxomatous human mitral heart valves.

Biochemical Journal, 1984
The collagens were studied in 13 normal and 19 myxomatous human mitral valves. The collagens of the valve were completely solubilized by using a method consisting of guanidinium chloride extraction, limited pepsin digestions and CNBr cleavage of the ...
