Fallacies of assessing mitral valve area by planimetry:
a) Inability to get a cut at the tip of the funnel
b) Inability to get a cut parallel to the orifice
c)
Multiple mitral regurgitation jets can be quantified by various methods like quantitative Doppler method, quantitative two dimensional method and PISA method applied to each jet separately.
