The risk of acute aortic events in patients with bicuspid aortic valve (BAV) constitutes a medical concern in terms of timing and surgical decision. During the past years, there has been a growing interest in the potential of microRNAs (miRNAs) as crucial epigenetic factors in multiple cellular processes associated with BAV aortopathy. Nevertheless, there are still challenges that need to be overcome before miRNAs could enter clinical practice, and further validation studies in larger and well-defined BAV cohorts are now required. This review aims at providing a comprehensive overview of the available data on the expression profiles and function of specific miRNAs in BAV aortopathy, evaluating miRNA signatures as potential molecular markers of disease. We also discuss the role of other novel classes of non-coding RNAs, including long non-coding RNAs and circular RNAs, in BAV-associated aortopathy, mainly regarding their possible implementation as diagnostic and prognostic markers.

Aortitis, defined as inflammation of the aorta, can lead to aneurysms and dissections. Intra-operative sampling is essential for diagnosis, with many cases presenting asymptomatically as clinically isolated aortitis. Previous studies investigating aortitis in major aortic surgery have been limited by low intra-operative sampling.

Bicuspid aortic valve (BAV), the most common congenital cardiac anomaly, predisposes individuals to aortic stenosis and regurgitation due to valve degeneration. Abnormal hemodynamics, arterial wall characteristics, and genetic factors contribute to ascending aorta dilatation, potentially leading to severe complications like aortic dissection. Presently, the most recent guidelines propose that individuals with BAV requiring valve replacement due to valve dysfunction should undergo simultaneous replacement of the ascending aorta when the diameter of aortic dilatation exceeds 4.

Hypertension and bicuspid aortic valve (BAV) are key clinical factors that may affect local biomechanical properties of ascending thoracic aortic aneurysms (ATAAs). This study sought to investigate regional differences in biaxial mechanical properties of the ATAAs for the hypertensive patients with BAV. Fresh ATAA samples were harvested from 16 hypertensive patients (age, 66 ± 9 years) undergoing elective aortic surgery.

Background: Aortic dilation, cardiac malformations and hypertension are known risk factors for aortic dissection in Turner syndrome (TS). In the current guidelines, rapid growth of the aorta has been added as a risk marker. This study aimed to estimate the growth of the ascending aorta over time, to identify risk factors of aortic growth, and to describe aortic complications in TS.

Background: Bicuspid aortic valve (BAV) is the most common congenital heart defect (reported incidence of 0.5%-2%) and is commonly associated with proximal aortic dilation. Patients with severe aortic stenosis (AS) of BAV have been shown to have worse pre-operative left ventricular (LV) function as well as a higher incidence of post-operative heart failure hospitalization when compared with analogous patients with tri-leaflet aortic valve disease.
