KLF5 Downregulation Links Impaired BNIP3‐Mediated Mitophagy to Inflammatory Valve Remodeling in Calcific Aortic Valve Disease

Advanced Science, EarlyView.
In human CAVD, KLF5 is reduced in VIC‐rich regions and remodeling/stress‐associated VIC states. In VICs, KLF5 sustains BNIP3 promoter activity and BNIP3‐mediated mitophagy, thereby limiting cytosolic mtDNA accumulation. KLF5 loss weakens mitochondrial quality control and enhances mtDNA‐sensitive STING/NF‐κB/NLRP3 inflammatory signaling under osteogenic

Quadricuspid Aortic Valve: A Rare Congenital Anomaly [PDF]

Journal of Clinical and Diagnostic Research, 2018
Quadricuspid Aortic Valve (QAV) is a rare, but well-recognised congenital anomaly, which may result in significant aortic regurgitation. We report a case of asymptomatic young male who was inadvertently diagnosed with QAV with moderately severe aortic ...

CD34+ Progenitors Promote Ageing‐Associated Valve Sclerosis through the PDGFR–JNK–JUNB Pathway

Advanced Science, EarlyView.
In age‐related aortic valve sclerosis, non‐bone marrow CD34+ progenitor valvular interstitial cells (VICs) undergo transdifferentiation into periostin+ myofibroblast‐like VICs via the PDGFR‐JNK‐JUNB axis, driving leaflet thickening and fibrosis. Ablating non‐bone marrow CD34+ cells attenuates this remodeling.

Mid- and Longterm Neo-Aortic Valve Regurgitation after Jatene Surgery: Prevalence and Risk Factors

Arquivos Brasileiros de Cardiologia, 2018
Background: Jatene surgery became the surgical procedure of choice to repair transposition of the great arteries (TGA) in neonates and infants. Late complications, mainly related to the pulmonary outflow tract and coronary arteries, are well known.

Hypertension, aortic stenosis, and aortic regurgitation [PDF]

Annals of Translational Medicine, 2018
The prevalence of hypertension (1) and of valvular aortic stenosis (2) increase with age, and both hypertension (3,4) and valvular aortic stenosis (5) cause left ventricular hypertrophy. Both hypertension (1,3) and valvular aortic stenosis (2,6) are also associated with an increased incidence of cardiovascular events and mortality. Hypertension (either

Implantable Systems for Cardiovascular Treatment and Monitoring: Comparative Insights From Intracardiovascular and Extracardiovascular Technologies

Advanced Intelligent Systems, EarlyView.
A unifying device–cardiovascular interface framework is presented to classify implantable cardiovascular technologies as intracardiovascular blood‐contacting systems or extracardiovascular tissue‐only and blood‐handling architectures. Cross‐class comparison across shared semiquantitative criteria, including blood‐contact burden, biomimicry ...

Unusual cause of central aortic prosthetic regurgitation during transcatheter replacement

Revista Portuguesa de Cardiologia, 2016
Transcatheter aortic valve replacement (TAVR) is an increasingly common procedure for the treatment of aortic stenosis in elderly patients with comorbidities that prevent the use of standard surgery.

COX14 Variants Are Associated With Mitochondrial Complex IV Deficiency Nuclear Type 10 (MC4DN10)

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT COX14 encodes a transmembrane protein essential for cytochrome c oxidase (COX) complex assembly. A homozygous missense variant in COX14 was reported in three siblings from a single consanguineous family with severe, fatal infantile mitochondrial complex IV deficiency nuclear type 10 (MC4DN10; MIM# 619053).

Echocardiographic assessment of aortic regurgitation: a practical guideline from the British Society of Echocardiography

Echo Research and Practice
Aortic regurgitation is the third most common valve lesion with increasing prevalence secondary to an ageing population. Transthoracic echocardiography plays a vital role in the identification and assessment of aortic regurgitation and proves essential ...

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.
