Calculation of eroa by pisa method. Pisa proximal isovelocity surface area is a phenomenon that occurs when liquid flows through a circular orifice. Here is an example calculation to assess the severity of mitral regurgitation using the proximal isovelocity surface area pisa method which employs a form of the continuity equation. Note the aliasing velocity.
