5. Mitral valve replacement for mitral stenosis: 15 years single center experience

Journal of the Saudi Heart Association, 2016
Mitral valve replacement (MVR) with either a bioprosthetic or a mechanical valve is the treatment of choice for severe mitral stenosis. This study aimed to evaluate and compare the early and late outcome of mitral valve replacement (mechanical versus ...

Factors Influencing Mortality after Bioprosthetic Valve Replacement; A Midterm Outcome [PDF]

Journal of Cardiovascular and Thoracic Research, 2013
Introduction: Although valve repair is applied routinely nowadays, particularly for mitral regurgitation (MR) or tricuspid regurgitation (TR), valve replacement using prosthetic valves is also common especially in adults.

Bioinspired Passive Flow Routing to Mitigate Thrombosis in Prosthetic Heart Valves and Cardiovascular Devices

Advanced Science, Volume 13, Issue 53, 24 September 2026.
Bioinspired passive flow routing mitigates thrombosis in cardiovascular devices by redirecting a small fraction of forward flow into stagnation‐prone regions. Inspired by avian alula and aircraft slat mechanisms, strategically placed routing channels restore washout around mechanical heart valves, reducing low‐shear exposure by four orders of magnitude

Use of a sutureless aortic valve in reoperative aortic valve replacementCentral MessagePerspective

JTCVS Techniques, 2022
Objectives: Management of degenerated bioprosthetic aortic valves remains a challenge. Valve-in-valve transcatheter aortic valve replacement (AVR) has limited utility in the presence of small annuli/prosthetic valves.

Comparative Outcomes of Transcatheter Versus Surgical Pulmonary Valve Replacement in Adults With Congenital Heart Disease

Catheterization and Cardiovascular Interventions, Volume 108, Issue 3, Page 792-800, September 1, 2026.
ABSTRACT Background Pulmonary valve replacement is frequently required in adults with congenital heart disease (CHD). Comparative real‐world outcomes between percutaneous transcatheter pulmonary valve implantation (TPVR) and surgical pulmonary valve replacement (SPVR) remain incompletely characterized. We evaluated outcomes and resource utilization for

Consecutive Emergency Carotid Artery Stenting and Transcatheter Aortic Valve Replacement in a Patient With Cardiogenic Shock: A Case Report

Catheterization and Cardiovascular Interventions, Volume 108, Issue 3, Page 1047-1051, September 1, 2026.
ABSTRACT Severe aortic stenosis (AS) carries a poor prognosis when symptomatic, particularly in cardiogenic shock (CS). Emergency transcatheter aortic valve replacement (TAVR) is rarely performed but may represent a rescue therapy. Coexistent carotid artery stenosis (CAS) further increases procedural risk.

Comparative analysis of ovine and human aortic valve tissue for bioprosthetic valve development using relaxation tests and numerical simulation

Scientific Reports
As the demand for aortic valve prostheses grows, optimizing their mechanical performance and durability is essential. While mechanical valves offer longevity, their need for lifelong anticoagulation limits their use, making bioprosthetic valves a ...
