Proximal isovelocity surface area should be routinely measured in evaluating mitral regurgitation: a core review.

Abstract

The proximal isovelocity surface area (PISA) measurement, also known as the "flow convergence" method, can be used in echocardiography to estimate the area of an orifice through which blood flows. It has many applications, but this review focuses only on its use in the intraoperative evaluation of mitral regurgitation. In that setting, PISA provides a… (More)
