A an example of the shape of the doppler pisa shell which does not resemble a true hemispheric pisa but is ‘urchinoid’ in shape due to the direction of flow black arrows, b. By the continuity equation, eroa is calculated as flow divided by peak velocity at the exact time when radius was measured, or qv max severe tr ≥ 0. Such patients usually have severe mr substantiated by other echocardiographic findings and clinical decision making is straightforward. Pisa proximal isovelocity surface area is a phenomenon that occurs when liquid flows through a circular orifice.
