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 ...

Vaginal delivery in a patient with asymptomatic severe aortic stenosis: a case report [PDF]
, 2023 Heart disease complicates about 1-4% of all pregnancies of which valvular heart disease is the commonest cause. In developing countries, congenital heart diseases are commonly first detected during pregnancy.

Automatic Aortic Valve Pathology Detection from 3-Chamber Cine MRI with Spatio-Temporal Attention Maps [PDF]
arXiv, 2023 The assessment of aortic valve pathology using magnetic resonance imaging (MRI) typically relies on blood velocity estimates acquired using phase contrast (PC) MRI. However, abnormalities in blood flow through the aortic valve often manifest by the dephasing of blood signal in gated balanced steady-state free precession (bSSFP) scans (Cine MRI).

Vortex dynamics and transport phenomena in stenotic aortic models using Echo-PIV [PDF]
, 2020 In this work, we propose a novel approach which combines ultrasound with Eulerian and Lagrangian descriptors, to analyse blood flow dynamics and fluid transport in stenotic aortic models with morphology, mechanical and optical properties close to those of real arteries.

Transcatheter Aortic Valve Implantation in Dialysis Patients [PDF]
, 2012 Background/Aims: Transcatheter aortic valve implantation (TAVI) has emerged as a new therapeutic option for high-risk patients. However, dialysis patients were excluded from all previous studies.

Effects of stenotic aortic valve on the left heart hemodynamics: a fluid-structure-electrophysiology approach [PDF]
arXiv, 2021 The aortic valve is a three-leaflet passive structure that, driven by pressure differences between the left ventricle and the aorta, opens and closes during the heartbeat to ensure the correct stream direction and flow rate. In elderly individuals or because of particular pathologies, the valve leaflets can stiffen thus impairing the valve functioning ...

International Journal of Critical Illness and Injury Science, 2018 A case of a 52-year-old male with ventricular tachycardia and atrial fibrillation associated with aortic stenosis is outlined. Focused cardiac ultrasound images obtained in the emergency department are presented. A discussion of aortic stenosis and emergency ultrasound in the above clinical context is included.Cooper RD, Macedo J, Bahner DP.

Segmentation of Aortic Vessel Tree in CT Scans with Deep Fully Convolutional Networks [PDF]
arXiv, 2023 Automatic and accurate segmentation of aortic vessel tree (AVT) in computed tomography (CT) scans is crucial for early detection, diagnosis and prognosis of aortic diseases, such as aneurysms, dissections and stenosis. However, this task remains challenges, due to the complexity of aortic vessel tree and amount of CT angiography data. In this technical

Degenerative aortic stenosis [PDF]
BMJ, 2008 #### Summary points Aortic stenosis is the most common valvular lesion in Europe and North America. It primarily presents as calcific aortic stenosis in 2-7% of the population aged >65 years.1 About 80% of adult patients with symptomatic aortic stenosis are male.
