Purpose
|
To calculate mitral valve area
using the proximal isovelocity surfaface area (PISA) method (also known as
flow convergence method). |
Technical Hints
|
PISA method calculates effective
orifice area irrespective whether the orifice is stenotic, regurgitant of
otherwise. To calculate aortic valve area PISA use general PISA method by
