2D echo provides normative mitral annular area and dynamics in healthy subjects; extends reference standards but leaves clinical application in disease open.
Does two-dimensional echocardiography allow for the reconstruction and measurement of mitral valve annulus size and motion in normal subjects?
Two-dimensional echocardiography can reliably reconstruct the mitral valve annulus, demonstrating presystolic and systolic narrowing in normal human subjects.
Ormiston et al. (1981) studied this question.
