How Good is Stroke Volume Calculation by the Doppler Continuity Method?

Introduction: Echocardiographic transvalvular stroke volume (SV) calculations are used to quantify regurgitant volume and shunt ratios. Calculations of stroke volume (SV) depend on the accuracy of valve diameter measurement and spectral Doppler velocity recording. We sought to compare how well SV calculated across each of the 4 intracardiac valve correlated with each other.
