Development and evaluation of X‐ray lithophanes as test objects for interventional procedure simulation

Medical Physics, Volume 53, Issue 11, November 2026.
Abstract Background In the growing field of interventional radiology, emerging technologies implement the use of artificial intelligence (AI) to help tackle growing demands for treatment. Due to the anatomical differences in animals, volunteers offer the most realistic training and testing scenario, however safety considerations restrict rapid ...

Invasive electrophysiological testing to predict and guide permanent pacemaker implantation after transcatheter aortic valve implantation: A meta-analysis

Heart Rhythm O2, 2023
Background: Atrioventricular conduction abnormalities after transcatheter aortic valve implantation (TAVI) are common. The value of electrophysiological study (EPS) for risk stratification of high-grade atrioventricular block (HG-AVB) and guidance of ...

TAVI-in-TAVI in a patient with morquio syndrome: a case report

European Heart Journal - Case Reports
Abstract Background Morquio syndrome (MPS IV) is a rare multi-systemic disorder with significant cardiovascular implications, including early-onset valvular disease. Due to the improved life expectancy, these patients could require complex interventional solutions such as TAVI-in-TAVI procedure.

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 ...

Antithrombotic therapy in TAVI.

Journal of geriatric cardiology : JGC, 2018
Transcatheter aortic valve implantation (TAVI) carries a significant thromboembolic and concomitant bleeding risk, not only during the procedure but also during the periprocedural period. Many issues concerning optimal antithrombotic therapy after TAVI are still under debate.

Sheath‐to‐Artery Diameter Ratio: A Robust Predictor of Early Access‐Site Adverse Events in Percutaneous Procedures

Catheterization and Cardiovascular Interventions, Volume 108, Issue 4, Page 1622-1629, October 1, 2026.
ABSTRACT Background Vascular access site complications (VASCs) remain an important source of morbidity following percutaneous interventions. Although the sheath‐to‐femoral artery ratio is a recognized risk factor in transcatheter aortic valve implantation (TAVI), its role across a broader range of femoral procedures is less well defined.

Clinical Outcomes of the Allegra Transcatheter System in Bioprosthetic Aortic Valve Failure: A Multicentre Valve‐in‐Valve Registry

Catheterization and Cardiovascular Interventions, Volume 108, Issue 4, Page 1690-1697, October 1, 2026.
ABSTRACT Introduction The prevalence of bioprosthetic aortic valve failure is increasing due to the broader use of bioprosthetic valves, both surgical and transcatheter, and an ageing population. Registry data indicate a higher risk of coronary obstruction and elevated gradients following valve‐in‐valve transcatheter aortic valve implantation (TAVI ...
