Aortic valve disease: Novel animal models for advancing our understanding of the underlying mechanisms

Animal Models and Experimental Medicine, Volume 9, Issue 10, Page 1964-1981, October 2026.
Due to the complex pathophysiology of aortic valve disease (AVD) and the resulting lack of effective pharmacotherapy, existing animal models are valuable research tools, but each has its own strengths and limitations. This review systematically surveys the major AVD models, compares their induction methods, pathological features, advantages and ...

Validation of an Automated Artificial Intelligence‐Driven Planner for Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, Volume 108, Issue 4, Page 1473-1481, October 1, 2026.
ABSTRACT Background Preprocedural planning with multislice computed tomography (MSCT) is an essential prerequisite for successful transcatheter aortic valve replacement (TAVR). However, preprocedural planning is time‐consuming and may contain clinically meaningful interobserver variability.

Effect of the Mitral Valve on the Intra Ventricular Hemodynamics

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 10, October 2026.
Patient‐specific Computational Fluid Dynamics was employed to analyze the impact of four distinct mitral valve geometries, varying in area and jet direction, on left‐ventricular flow and overall heart efficiency. The valve design influenced intraventricular vortices, turbulent kinetic energy, and dissipation.

Infective Endocarditis Diagnosed by Emergency Physicians Using Cardiac POCUS: A Case Series

Australasian Journal of Ultrasound in Medicine, Volume 29, Issue 3, August 2026.
ABSTRACT Introduction Emergency physicians (EPs) are acquiring ever‐increasing expertise in cardiac point‐of‐care ultrasound (POCUS). We compiled this case series to demonstrate current practice by EPs diagnosing infective endocarditis (IE) using POCUS.

Clinical and Echocardiographic Outcomes After Implantation of the ALLEGRA Transcatheter Valve Using the Fully Repositionable IMPERIA Delivery System: One‐Year Results of the EMPIRE I Study

Catheterization and Cardiovascular Interventions, Volume 108, Issue 2, Page 540-547, August 1, 2026.
ABSTRACT Background The EMPIRE I study assessed the early (30 days) safety and efficacy of a new fully repositionable delivery system (IMPERIA) for the commercially available ALLEGRA transcatheter aortic valve in patients with either severe native aortic stenosis or a degenerated surgical bioprosthesis.

Evaluation of aortic bioprosthesis stenosis by multidetector CT.

, 2012
Because visualization the bioprosthesis leaflets is often hampered by shadowing artifacts from to the metal in the annulus or the struts, visualization and determination of the etiology of bioprosthesis valve dysfunction may be often difficult by ...
