From: Severity of aortic regurgitation assessed by area of vena contracta: a clinical two-dimensional and three-dimensional color Doppler imaging study

Figure 1

Measurement of two-dimensional vena contracta area (2DVCA) using two-dimensional color Doppler imaging. Parasternal long-axis view (left). Cross-sectional plane of the proximal flow convergence (right, top); Cross-sectional plane of the vena contracta (right, middle). The narrowest area of the jet was measured as 2DVCA (arrow). Care was taken not to include the surrounding blurred color signals as VCA by checking both color and color-suppressed images. Cross-sectional plane of the distal expansion of the regurgitant jet spray (right, bottom). PSLAX, parasternal long-axis view; PSSAX, parasternal short-axis view; Ao, aorta; LV, left ventricle.
