Comparison Between the Acurate Neo and the Acurate Neo 2 Transcatheter Heart Valve System: Impact of Midframe Under‐Expansion

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter aortic valve implantation (TAVI) with the Acurate Neo has been linked to a significant incidence of paravalvular leakage (PVL), addressed by the Acurate Neo 2 incorporating an active sealing skirt. Recent findings suggest that midframe under‐expansion is associated with worse outcomes.

Non-contrast ultrasound assessment of blood flow in clinical practice

Journal of Ultrasonography
Since the first clinical use of ultrasound in the 1940s, significant advancements have been made in its applications. Color Doppler imaging and power Doppler imaging are considered the first and second generations of flow ultrasound assessment tools ...

Role of ultrasound with color doppler in acute scrotum management

Journal of Family Medicine and Primary Care, 2014
An acute scrotum is defined as acute pain with or without scrotal swelling, may be accompanied by local signs or general symptoms. Acute scrotal pain is a medical emergency. Depending on cause, the management is entirely different. Torsion of testis and strangulated hernia are surgical emergency; whereas, epididymo-orchitis is treated by medicines ...

The effectiveness and cost-effectiveness of ultrasound locating devices for central venous access: a systematic review and economic evaluation [PDF]

, 2003
Background: Approximately 200,000 central venous access (CVA) procedures are performed annually in the NHS. CVA has traditionally been achieved by the landmark method of passing the needle along the anticipated line of the relevant vein using ...

Comparative Study of Gas and Liquid Flow in Packed Beds Using Phase‐Contrast MRI

Chemie Ingenieur Technik, EarlyView.
This work presents applications of phase‐contrast magnetic resonance imaging (MRI) to investigate fluid flow fields and temperature in packed beds. Comparison of ethane (C2H6) gas flow with that of water flow is done at similar flow conditions. The temperature of water is also measured using MRI.

Prevalence of transthyretin cardiac amyloidosis in undifferentiated heart failure with preserved ejection fraction

ESC Heart Failure, Volume 12, Issue 2, Page 1176-1182, April 2025.
Abstract Aims Transthyretin amyloid cardiomyopathy (ATTR‐CM) is an increasinglyrecognized cause of heart failure with preserved ejection fraction (HFpEF), which may be diagnosed non‐invasively using 99mTc 3,3‐diphosphono‐1,2‐propanodicarboxylic acid (DPD) scintigraphy‐based diagnostic criteria.

Imaging of blood flow and oxygen state with a multi-segment optoacoustic ultrasound array

Photoacoustics, 2018
Changes in hemodynamic parameters are directly linked to biological function and physiological activity. Characterization of hemodynamics is commonly performed by Doppler ultrasound, which provides accurate measurements of blood flow velocity.
