Management of Intracranial Hemorrhage in the Setting of Mechanical Heart Valve Replacement Therapy

Applied Mechanics, 2023
The management of an intracranial hemorrhage in patients receiving anticoagulant therapy presents a significant challenge for medical professionals. Anticoagulant treatment is intended to prevent blood clotting, but it can worsen active brain bleeds ...

Mid-term results of mitral valve repair using flexible bands versus complete rings in patients with degenerative mitral valve disease: a prospective, randomized study

Journal of Cardiothoracic Surgery, 2017
Background We aimed to compare the outcomes of mitral valve repair with flexible band (FB) versus complete semirigid ring (SR) in degenerative mitral valve disease patients.

Multimodality imaging in the diagnostic approach to a patient with carcinoid heart disease involving four heart valves

Clinical Case Reports, 2022
Carcinoid heart disease is a rare condition that occurs in less than half of patients with carcinoid syndrome. The disease mainly affects right‐sided heart valves; however, in 5%–10%, it can also involve left‐sided valves.

Controlled Comparison of Simulated Hemodynamics across Tricuspid and Bicuspid Aortic Valves [PDF]

, 2021
Bicuspid aortic valve is the most common congenital heart defect, affecting 1-2% of the global population. Patients with bicuspid valves frequently develop dilation and aneurysms of the ascending aorta. Both hemodynamic and genetic factors are believed to contribute to dilation, yet the precise mechanism underlying this progression remains under debate.

Staphylococcus aureus endocarditis: distinct mechanisms of bacterial adhesion to damaged and inflamed heart valves.

European Heart Journal, 2019
AIMS The pathogenesis of endocarditis is not well understood resulting in unsuccessful attempts at prevention. Clinical observations suggest that Staphylococcus aureus infects either damaged or inflamed heart valves.

Advances in xenogeneic donor decellularized organs: A review on studies with sheep and porcine-derived heart valves. [PDF]

Bioeng Transl Med
Heart valve replacement surgeries are performed on patients suffering from abnormal heart valve function. In these operations, the problematic tissue is replaced with mechanical valves or with bioprosthetics that are being developed.

A Deep Learning Framework for Design and Analysis of Surgical Bioprosthetic Heart Valves

Scientific Reports, 2019
Bioprosthetic heart valves (BHVs) are commonly used as heart valve replacements but they are prone to fatigue failure; estimating their remaining life directly from medical images is difficult.

Clinical performance of decellularized heart valves versus standard tissue conduits: a systematic review and meta-analysis

Journal of Cardiothoracic Surgery, 2020
Background Valve replacement surgery is the definitive management strategy for patients with severe valvular disease. However, valvular conduits currently in clinical use are associated with significant limitations.

Evaluation of pliable bioresorbable, elastomeric aortic valve prostheses in sheep during 12 months post implantation

Communications Biology, 2023
Pliable microfibrous, bioresorbable elastomeric heart valve prostheses are investigated in search of sustainable heart valve replacement. These cell-free implants recruit cells and trigger tissue formation on the valves in situ. Our aim is to investigate

Modern view on calcification of xenogenic bioprosthetic heart valves and their anti-calcification treatment strategies

Трансплантология (Москва), 2023
Aim. The aim of this review was to analyze publications describing studies focusing on the pathophysiological mechanisms of calcification of bioprosthetic heart valves, and to substantiate new and promising methods of calcification prevention for the ...
