Planimetry for measuring MVA is performed in which imaging plane?

Explanation:
Planimetry of the mitral valve area requires tracing the actual opening of the mitral orifice from a face-on view. The parasternal short-axis view at the level of the mitral valve provides this en-face alignment, allowing you to trace the inner edge of the opening during diastole when the orifice is widest. Other views don’t present the orifice in true planimetric orientation, making accurate tracing unreliable. So the imaging plane used for planimetry is the parasternal short-axis view at the mitral valve level.
