Calculation of stenotic valve area can aide in the determination of the severity of the lesion. While use of Doppler derived pressure gradients are widely used and easily interpreted, certain situations may make these measurements less reliable. The purpose of this paper is to demonstrate the technique for measuring the stenotic valve area and illustrate situations where this added information may be of diagnostic benefit.
