A Case of Isolated Congenital Double-Orifice Mitral Valve [PDF]

, 1998
Double-orifice mitral valve is a relatively rare congenital abnormality, usually discovered at autopsy or surgery. In most cases, the double-orifice mitral valve causes no hemodynamic effects, sometimes it is regurgitant, and rarely is stenotic ...

Color Doppler velocity accuracy proximal to regurgitant orifices: influence of orifice aspect ratio

, 1999
Many noninvasive methodologies used for the accurate evaluation of valvular regurgitation require precise velocity measurements from ultrasound instruments.

CT predicts intraprocedural hemodynamics with computational fluid dynamics in TMVR-ineligible patients undergoing M-TEER

Frontiers in Cardiovascular Medicine
BackgroundHemodynamic outcomes in patients undergoing transcatheter mitral edge-to-edge repair (M-TEER) are difficult to predict. Computational fluid dynamics (CFD) is frequently used in biomedical engineering to simulate blood flow patterns under ...

Utilization and characterization of the Medtronic Mosaic in a relevant chronic ovine model of surgical tricuspid valve replacement

Scientific Reports
Approaches to treating tricuspid valve disease are at the forefront of current clinical investigation. Utilization of an established large animal model to evaluate novel valves is required for regulatory approval prior to clinical investigation.

Non-circular orifice flowfields in valvular regurgitation

, 1995
The proximal flowfield (PFF) is a primary tool in quantifying valvular regurgitation when using Color Doppler Ultrasound (CDU) in-vivo. Regurgitant flow calculations are made using the proximal isovelocity surface area (PISA) method and the aliasing ...
