WebMitral valve area (MVA) measurement by three-dimensional transesophageal echocardiography (3D-TEE) has a crucial role in the evaluation of mitral stenosis (MS) severity. Three-dimensional direct (3D-direct) planimetry has been proposed as a new technique to measure mitral valve area. This study aime … WebAim: One limitation for a wider use of the proximal isovelocity surface area method (PISA) for the evaluation of the mitral valve area (MVA) in patients with mitral stenosis (MS) is the requirement of an angle correction factor (angle alpha between the mitral leaflets) which cannot be obtained using the machine's built-in software and requires a manual …

WebDec 17, 2024 · Because stenosis results from mitral annular calcification encroaching on the leaflet bases, without involvement of the leaflet tips, PMBC is not beneficial. Severe mitral annular calcification can make secure implantation of a surgical prosthesis challenging and may result in residual MS following valve replacement. Therefore, in … WebAbstract. Aim: One limitation for a wider use of the proximal isovelocity surface area method (PISA) for the evaluation of the mitral valve area (MVA) in patients with mitral stenosis … WebTwo-dimensional echocardiographic (2-D) planimetry and the Doppler pressure half-time (PHT) method have been used to estimate mitral valve area (MVA) in patients with mitral stenosis (MS).
