Small vesicles, big potential: A review of innovative exosome delivery and molecular mechanisms in preclinical myocardial infarction models

Animal Models and Experimental Medicine, EarlyView.
This narrative review discusses animal models of exosome‐based myocardial infarction treatments. Emerging techniques aim to improve exosome stability, targeting, and bioavailability for MI treatment as drug delivery vehicles and regenerative mediators that promote myocardial regeneration. Abstract Exosomes have emerged as promising therapeutic carriers,

Surgical approach for cardiac surgery in a patient with tracheostoma [PDF]

, 1998
The thoracic approach for cardiac surgery in a patient with a tracheostoma can result in difficult problems, such as mediastinitis, stoma necrosis or inadequate operative exposure. We present a distinct approach consisting of an incision at

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 ...

Comparative study of wall shear stress at the ascending aorta for different mechanical heart valve prostheses [PDF]

, 2019
An experimental study is reported which investigates the wall shear stress (WSS) distribution in a transparent model of the human aorta comparing a bileaflet mechanical heart valve (BMHV) with a trileaflet mechanical heart valve (TMHV) in physiological ...

Predicting Coronary Occlusion Risk during Redo‐TAVR at First TAVR: Asymmetric Calcification Causes Failure

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background and Aims Predicting coronary artery occlusion due to sinus sequestration (SS) during a second transcatheter aortic valve (TAV) procedure using pre‐procedural computed tomography (CT) after the first TAV replacement (TAVR) is underreported.

Human tissue valves in aortic position: determinants of reoperation and valve regurgitation [PDF]

, 2001
BACKGROUND: Human tissue valves for aortic valve replacement have a limited durability that is influenced by interrelated determinants. Hierarchical linear modeling was used to analyze the relation between these determinants
