Dual Illumination Planar Doppler Velocimetry using a Single Camera [PDF]

, 2003
A Planar Doppler Velocimetry (PDV) illumination system has been designed which is able to generate two beams, separated in frequency by about 600 MHz. This allows a common-path imaging head to be constructed, using a single imaging camera instead of ...

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.

Early Experience With Evoque Transcatheter Tricuspid Valve Replacement in Carcinoid Heart Disease

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Tricuspid regurgitation (TR) is nearly universal in carcinoid heart disease (CHD), but surgical replacement carries significant risk, and CHD was excluded from the landmark TRISCEND II trial. We present seven patients with CHD undergoing Evoque transcatheter tricuspid valve replacement (TTVR) at two tertiary centers.
