Background: To determine the impact of circulating miRNA and protein activity on the severity of ascending aortic dilatation in patients with bicuspid (BAV) and tricuspid aortic valve (TAV). Methods: By reverse transcription polymerase chain reaction, exosomal circulating expression levels (versus healthy aorta) of miRNAs and absolute levels of transforming growth factor β (TGF-β), matrix metalloproteinases (MMP-2, -3 and -9), tissue inhibitors (TIMP-1, -2, -3 and -4), and soluble receptors for advanced glycation end products AGEs (sRAGE) were evaluated in ascending dilated aortas of 71 patients with different valve morphotype. Results: Less-dilated ascending aorta exhibited a specific miRN…

An overview of the molecular mechanisms underlying development and progression of bicuspid aortic valve disease
2019
Bicuspid aortic valve (BAV) is a common congenital heart malformation frequently associated with the development of aortic valve diseases and severe aortopathy, such as aortic dilatation, aneurysm and dissection. To date, different genetic loci have been identified in syndromic and non- syndromic forms of BAV. Among these, genes involved in the regulation of extracellular matrix remodelling, epithelial to mesenchymal transition and nitric oxide metabolism appear to be the main contributors to BAV pathogenesis. However, no- single gene model explains BAV inheritance, suggesting that more factors are simultaneously involved. In this regard, characteristic epigenetic and immunological profiles…
Bicuspid aortic valve and sports: From the echocardiographic evaluation to the eligibility for sports competition
2021
Bicuspid aortic valve (BAV) is the most common congenital heart defect in adults. Although a BAV may remain without clinical consequences for a lifetime, it can deteriorate in aortic valve stenosis and regurgitation and aortic dilatation. Unfortunately, the impact of regular training on patients with BAV and its natural course is not fully understood, although preliminary evidence suggests that the progression of valvular disease occurs primarily in an independent manner from sports practice. The current review aims to report how to perform a comprehensive echocardiographic examination in athletes with BAV and analyze the current literature on the influence of sports practice and how it imp…
