Video 14.11 Color Doppler of typical congenital mitral stenosis from an apical 4-chamber view
Color Doppler of typical congenital mitral stenosis from an apical 4-chamber view. Note the flow acceleration in the distal aspect of the inflow with the proximal isovelocity surface area (PISA) aliased lines representing increasing velocity “shells” as the flow approaches the small orifice.
