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 …
