MVQ definition
Examples of MVQ in a sentence
The present study was designed to compare the mitral valve geometry measurements obtained prospectively with MDCT and 3D TEE using MVQ software.
Off-line analysis of the 3D TEE images was performed with a novel post-processing Mitral Valve Quantifica- tion (MVQ) software (QLAB cardiac 3DQ, Philips Medical System, Andover, MA, USA).
MVQ helps to build a 3D model step by step, of the mitral valve annulus, anterior and posterior leaflets, leaflet segmentation, coapta- tion line and potential coaptation defects, as well as mitral valve spatial relationship with the aortic valve.
The accuracy of the novel MVQ software to assess mitral valve geometry was evaluated using MDCT as a reference method.
The measurements of the mitral valve apparatus performed with the MVQ software included: the in- tercommissural and antero-posterior annular diameters and the mitral annular area, the length, angle and area of the anterior and posterior leaflet, the tenting height and the coaptation leaflet angle and the angle between the mitral annulus and the aortic annulus.
All images were digitally stored for off-line analysis with the MVQ software (QLAB cardiac 3DQ, Philips Medical System, Andover, MA, USA).
The MVQ 3D model can be manipulated in the 3D space and overlaid on the anatomical 3D view of the mitral valve.
MVQ allows precise 3D quantification of the mitral valve geometry and associated structures based on acquired 3D TEE data.
By identifying 3D landmarks on multiplanar refor- mation planes, MVQ builds a 3D model of the mitral valve and the surrounding structures (Figure 1A).
