Sterile Aortic Root Abscess Mimicking Calcified Aortic Nodule: A Rare Case [PDF]

Journal of Clinical and Diagnostic Research, 2017
Aortic root abscess or aortic annular abscess is a serious complication of aortic valve endocarditis. It usually occurs in patients with prosthetic aortic valve and coagulase-negative staphylococcal endocarditis.

Immersed boundary-finite element model of fluid-structure interaction in the aortic root [PDF]

, 2015
It has long been recognized that aortic root elasticity helps to ensure efficient aortic valve closure, but our understanding of the functional importance of the elasticity and geometry of the aortic root continues to evolve as increasingly detailed in vivo imaging data become available.

CardioXNet: A Novel Lightweight Deep Learning Framework for Cardiovascular Disease Classification Using Heart Sound Recordings [PDF]

, 2020
The alarmingly high mortality rate and increasing global prevalence of cardiovascular diseases signify the crucial need for early detection schemes. Phonocardiogram (PCG) signals have been historically applied in this domain owing to its simplicity and cost-effectiveness.

Aortic regurgitation: A multimodality approach

Journal of Clinical Ultrasound, 2022
AbstractAortic regurgitation (AR) is a common valvular pathology. Multimodality noninvasive cardiovascular imaging is routinely used to assess the mechanism of AR, degree, and its hemodynamic impact on the cardiovascular system. Collecting this information is crucial in establishing the prognosis and in guiding patient management and follow‐up.

A Novel Protein NAB1‐356 Encoded by circRNA circNAB1 Mitigates Atrial Fibrillation by Reducing Inflammation and Fibrosis

Advanced Science, EarlyView.
The circRNA circNAB1 is downregulated in AF patient. Silencing circNAB1 promotes collagen deposition and inflammation, whereas overexpression reduces AF susceptibility. circNAB1 encodes the protein NAB1 356 that interacts with EGR1 to mitigate fibrosis and inflammation.

Estimate of genetic variants using CNV‐Seq for fetuses with oligohydramnios or polyhydramnios

Molecular Genetics &Genomic Medicine, Volume 11, Issue 1, January 2023., 2023
The overall detection rate of clinically significant findings was 8%, with 5.0% in the isolated group and 11.0% in non‐isolated group. Non‐isolated group especially oligohydramnios subgroup is inclined to obtained more pathogenicity genetic anomalies and to terminate their pregnancy outcome.

Awake Surgical Mitral Valve Repair after Transcatheter Aortic Valve Replacement

The Thoracic & Cardiovascular Surgeon Reports, 2021
Transcatheter aortic valve replacement has become a popular choice for cases with severe aortic stenosis. However, when severe mitral regurgitation is comorbid in high-risk patients with severe aortic stenosis, therapeutic options must be weighed for ...

Effect Of Coronary Bypass And Valve Structure On Outcome In Isolated Valve Replacement For Aortic Stenosis [PDF]

, 2012
Reports differ regarding the effect of concomitant coronary artery bypass grafting (CABG) in patients who undergo aortic valve replacement (AVR) for aortic stenosis (AS), and no reports have described the effect of aortic valve structure in patients who ...

Dynamic simulation of aortic valve stenosis using a lumped parameter cardiovascular system model with flow regime dependent valve pressure loss characteristics [PDF]

arXiv, 2022
Valvular heart diseases are growing concern in impoverished parts of the world, such as Southern-Africa, claiming more than 31 % of total deaths related to cardiovascular diseases. The ability to model the effects of regurgitant and obstructive lesions on the valve body can assist clinicians in preparing personalised treatments.

Bilateral coronary ostial stenosis and aortic regurgitation in a patient with cardiovascular syphilis [PDF]

, 2012
Cardiovascular syphilis is associated with the tertiary stage of syphilis infection; it involves the ascending aorta and can cause aortic aneurysm, aortic regurgitation, and coronary ostial stenosis. We report a surgical case of bilateral coronary ostial
