Dynamic Echocardiographic Imaging of a Valve-in-Valve Mitral Prosthesis

Case Reports in Radiology, 2022
Dynamic imaging of heart valves and specifically prosthetic valves is a central benefit of echocardiography. Most bioprosthetic heart valves degenerate over a given time and hence require repeat valve replacement which carries a significant risk of ...

Electropermanent Magnetic Muscles: Power‐Efficient, Low‐Voltage, Compact Magnetic Actuators to Power Wearables and Untethered Robots

Advanced Intelligent Systems, EarlyView.
This work presents compact, low‐voltage actuators based on electropermanent magnetic interactions. The actuators show good overall performance across key metrics and are implemented in wearable devices and untethered robots. Their ability to operate in different configurations and hold positions without energy input highlights their potential for ...

Morphological and morphometric aspects of the equine aortic valve: New insights for comparative studies in mammals

The Anatomical Record, EarlyView.
Abstract New data on the equine aortic valve obtained using advanced techniques is especially important given the greater availability of animal models for translational research. Here we characterized the morphological and morphometric aspects of the equine aortic valve from 60 healthy hearts collected at equine abattoirs.

Macrophage‐targeted cerium‐tannic acid metal‐polyphenol framework nanoenzyme promotes in situ heart valves regeneration through adaptive immunomodulation

BMEMat, EarlyView.
A novel nanoenzyme based on cerium ions‐tannic acid metal‐polyphenol framework (FCT) has been developed and loaded onto DHVs for targeting M1 macrophages to reduce their ROS level and reprogram macrophage phenotype, thereby eliminating inflammation, promoting endothelialization and adaptive matrix remodeling of scaffolds, offering a promising strategy ...

Incidence and Predictors of Hypoattenuated Thickening and Device‐Related Thrombus at Three Months Postprocedural CT Assessment Following Left Atrial Appendage Occlusion With Amplatzer Devices—A Single‐Center Cohort

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Left atrial appendage occlusion (LAAO) has become a valuable alternative to long‐term anticoagulation for stroke prevention in patients with non‐valvular atrial fibrillation (AF), especially in those at high bleeding risk. Hypoattenuated thickening (HAT) and device‐related thrombus (DRT) remain notable postprocedural concerns ...

Commissural Misalignment Following Valve‐in‐Valve Transcatheter Aortic Valve Implantation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Data on commissural misalignment (CMA) during valve‐in‐valve transcatheter aortic valve implantation (ViV‐TAVI) for valve failure after surgical aortic valve replacement (SAVR) is scarce. Aims To study the impact of CMA on clinical and hemodynamic outcomes following ViV‐TAVI for failed SAVR.
