Left ventricular remodeling and hypertrophy in patients with aortic stenosis:insights from cardiovascular magnetic resonance [PDF]

open access: yes, 2012
Background Cardiovascular magnetic resonance (CMR) is the gold standard non-invasive method for determining left ventricular (LV) mass and volume but has not been used previously to characterise the LV remodeling response in aortic stenosis. We sought to

[Aortic valve stenosis].

open access: yesVojnosanitetski pregled, 2003
There is a long latent period in the clinical course of aortic valve stenosis in adults. Symptoms usually occur in the case of critical stenosis, when aortic orifice area is under 0.7 cm2 (0.4 cm2/m2). In this study 78 patients with critical aortic valve stenosis were investigated.

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

open access: yesBMEMat, 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 ...

Rapid progression of aortic and mitral stenosis in a patient with AA amyloidosis: a case report [PDF]

open access: yes, 2019
Background: Aortic stenosis is a common finding in cardiac amyloidosis (CA). Younger patients often remain asymptomatic. If unrecognized, this can lead to serious complications such as heart failure.

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

open access: yesCatheterization 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.

Transcatheter, valve-in-valve transapical aortic and mitral valve implantation, in a high risk patient with aortic and mitral prosthetic valve stenoses

open access: yesAnnals of Cardiac Anaesthesia, 2015
Transcatheter valve implantation continues to grow worldwide and has been used principally for the nonsurgical management of native aortic valvular disease-as a potentially less invasive method of valve replacement in high-risk and inoperable patients ...

Prediction of Turbulent Shear Stresses through Dysfunctional Bileaflet Mechanical Heart Valves using Computational Fluid Dynamics

open access: yes, 2018
There are more than 300,000 heart valves implanted annually worldwide with about 50% of them being mechanical valves. The heart valve replacement is often a common treatment for severe valvular disease.

Inhibition of MAPK-Erk pathway in vivo attenuates aortic valve disease processes in Emilin1-deficient mouse model [PDF]

open access: yes, 2017
Aortic valve disease (AVD) is a common condition with a progressive natural history, and presently, there are no pharmacologic treatment strategies. Elastic fiber fragmentation (EFF) is a hallmark of AVD, and increasing evidence implicates developmental ...

Balloon‐Expandable Versus Self‐Expanding Valves in Low‐Flow, Low‐Gradient Aortic Stenosis: Does Valve Type Matter?

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The optimal choice between balloon‐expandable (BE) and self‐expanding (SE) transcatheter heart valves (THVs) in patients with low‐flow low‐gradient aortic stenosis (LFLG AS) undergoing transcatheter aortic valve replacement (TAVR) remains unclear.
