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.

Extremity Function After Transfemoral Transcatheter Aortic Valve Implantation: A TAVI XS Sub‐Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Physical decline after transcatheter aortic valve implantation (TAVI) is associated with worse outcomes. However, data on post‐TAVI extremity function are limited. This sub‐study of the TAVI XS trial aimed to assess extremity function after transfemoral TAVI, evaluate functional decline, compare outcomes between upper‐and lower ...
