RATES of permanent pacemaker implantation (PPI) exceed 20% in patients with aortic regurgitation (AR). A new retrospective ...

An approach for extracting the radial force load on an implanted stent from medical images is proposed. To exemplify the approach, a system is presented which computes a radial force estimation from ...

Objectives To investigate the prevalence and quantity of aortic valve calcium (AVC) in two large cohorts, stratified according to age and lipoprotein(a) (Lp(a)), and to assess the association between ...

Calcific aortic valve stenosis (CAVS) is a major health problem facing aging societies. The identification of osteoblast-like and osteoclast-like cells in human tissue has led to a major paradigm ...

Introduction Aortic stenosis is the most common cardiac valve pathology worldwide and has a mortality rate of over 50% at 5 years if left untreated. Transcatheter aortic valve implantation (TAVI) is a ...

The high number of frames enabled creation of precise area-time diagrams. Thus, the individual phases of aortic valve movement (rapid opening, slow valve closing, and rapid valve closing) could be ...

Built on the ACURATE valve platform, which has been implanted in nearly 80,000 patients globally to date, the ACURATE Prime valve system is engineered to improve long-term cardiac function and ...

NY Valves 2024 Up Next Presentation NY Valves 2024 Clinical Outcomes in Patients Referred for Transcatheter Mitral Valve Therapies at High-Risk for Left Ventricular Outflow Tract Obstruction Presenter ...

3.2 Model performance A total of 123 original CTA images were used for training, and 31 images were used for validation. We deployed nnU-Net 3D full resolution architecture to train our segmentation ...

Aortic valve repair offers an alternative to aortic replacement. While it restores function and alleviates symptoms, replacement may be needed in some cases due to severe damage or repair complexity.

In the initial study published in 2010, TAVR was shown to be superior to medical therapy for patients with severe AS who could not undergo surgery due to prohibitive risk. 1 Since then, multiple, ...

Abdominal aortic aneurysms, located in a lower section of the aorta, have "very clear risk factors" -- tending to occur in people in their late 60s and 70s, in smokers and people with high blood ...
