MetabolomicsMetabolomics Characterization of Human Calcific Aortic Valve Stenosis

BACKGROUND: Calcific aortic valve stenosis (CAVS) is the most prevalent valvular heart disease in developed countries with significant morbidity and mortality. Given the poor understanding of the pathophysiological processes leading to CAVS, we utilized a joint non-targeted metab...

MetabolomicsValvular lipidomic changes in progression of human calcific aortic valve stenosis
This study investigates lipid dysregulation in calcific aortic valve stenosis (CAVS) by analyzing lipid profiles in valve tissues from 99 patients across different disease severities (mild, moderate, severe) using liquid chromatography-mass spectrometry (LC-MS). The results reveal distinct lipid alt...

MetabolomicsEvidence of altered fatty acid metabolism in dogs with naturally occurring valvular heart disease and congestive heart failure

INTRODUCTION: Myxomatous mitral valve disease (MMVD) is the most common cardiac condition in adult dogs. The disease progresses over several years and affected dogs may develop congestive heart failure (HF). Research has shown that myocardial metabolism is altered in cardiac dise...

TranscriptomicsSingle cell sequencing of developing heart valves identifies novel cell populations and uncovers interstitial cell heterogeneity
This study has two main goals. The first is to define a gene expression atlas of heart valve cells and identify cell heterogeneity within postnatal heart valve development. The second is to identify interstitial cell populations involved in ECM remodeling during postnatal heart valve development. Ov...

TranscriptomicsTranscription profiling of mouse E12.5 AV cushion and E17.5 AV valve from wild-type FVB/N mice and in vitro cultured MC3T3 cells
E12.5 AV cushion and E17.5 AV valve from wild-type FVB/N mice and in vitro cultured MC3T3 cells; In the study we demonstrated shared gene expression in embryonic heart valve development and Osteoblast progenitor cells. The atrioventricular (AV) valves of the heart develop from undifferentiated mesen...

TranscriptomicsValvular heart disease and atrial fibrillation regulate microRNA expression profiles in left and right atria differently
Background: Chronic atrial fibrillation (AF) is a complication associated with the dilated atria of patients with valvular heart disease and contributes to worsened pathology. Methods and Results: Using microarray technology, we examined microRNA (miR) expression profiles in right and left atrial ap...

MetabolomicsMyocardial-intrinsic defects underlie an Rbfox-mediated zebrafish model of hypoplastic left heart syndrome
Hypoplastic left heart syndrome (HLHS) is characterized by underdevelopment of left sided structures including the ventricle, valves, and aorta1. Although the mechanisms of disease pathogenesis remain elusive due to a paucity of candidate genes and animal models, prevailing paradigm suggests that HL...

ProteomicsProteolytic degradation is the culprit behind a bioprosthetic heart valve failure
Whereas the risk factors for structural valve deterioration (SVD) of glutaraldehyde (GA)- treated bioprosthetic heart valves (BHVs) are well-studied, those responsible for the failure of next-generation BHVs fixed with alternative chemicals remain largely unknown. Here, we collected 11 ethylene glyc...

TranscriptomicsCellular plasticity and diversity during heart valve epithelial-to-mesenchymal transitions revealed using single-cell RNA-seq
We have generated scRNA-seq data from embryonic day (E)10.5 and E12.5 atrioventricular canals (primitive heart valves) to assess cellular diversity during the distinct epithelial-to-mesenchymal transitions (EMTs) from endocardium and epicardium that guide the formation of valve mesenchyme. Alongside...

TranscriptomicsCharacterization of Heart Valve Leaflets from Adult and Juvenile Rapacz Familial Hypercholesterolemic Swine
Rapacz Familial Hypercholesterolemic (RFH) swine have been used extensively in the vascular biology field as a robust model of complex atherosclerotic lesions. However, the heart valves from RFH swine have not been evaluated and it is unknown whether these animals develop calcific aortic valve disea...
