Impact of measurement location on direct mitral regurgitation quantification using four-dimensional flow cardiovascular magnetic resonance

Journal of Cardiovascular Magnetic Resonance
Background: Four-dimensional (4D) flow cardiovascular magnetic resonance (CMR) shows promise for quantifying mitral regurgitation (MR) by allowing for direct regurgitant volume (RVol) measurement using a plane precisely placed at the MR jet. However, the

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 ...

Three-dimensional field optimization method : clinical validation of a novel color doppler method for quantifying mitral regurgitation

, 2016
Background Assessment of mitral regurgitation (MR) severity by echocardiography is important for clinical decision making, but MR severity can be challenging to quantitate accurately and reproducibly.

A novel fully automated method for mitral regurgitant orifice area quantification

, 2013
BackgroundEffective regurgitant orifice area (EROA) in mitral regurgitation (MR) is difficult to quantify. Clinically it is measured using the proximal isovelocity surface area (PISA) method, which is intrinsically not automatable, because it requires ...
