Impact of Assuming a Circular Orifice on Flow Error Through Elliptical Regurgitant Orifices: Computational Fluid Dynamics and in Vitro Analysis of Proximal Flow Convergence

2022-08-01

Abstract excerpt

<h4>Purpose: </h4> Grounded in hydrodynamic theory, proximal isovelocity surface area (PISA) is a simplistic and practical technique widely used to quantify valvular regurgitation flow. PISA provides a relatively reasonable, though slightly underestimated flow rate for circular orifices. However, for elliptical orifices frequently seen in functional mitral regurgitation, PISA underestimates the flow rate. Based on...
