Pulmonary regurgitation PISA
PISA fields are compact by default and appear when data are entered or report density is expanded.

Simple approach
Use PISA only when the flow convergence shell is well seen. Enter proximal radius, aliasing velocity, regurgitant Vmax, and regurgitant VTI; the derived EROA, regurgitant flow, and regurgitant volume follow.
Detailed tutorial
PISA can quantify PR, but pulmonary valve geometry and RVOT imaging can make it difficult. Confirm that the convergence zone is hemispheric enough for the assumptions to be useful.
If PISA is unreliable, leave the fields empty and rely on integrated PR grade, ED-Doppler, RV size/function, and prior-study comparison.
