N2 - Background Three-dimensional color Doppler echocardiography has been used to assess cardiac blood flow in experimental settings. We tested whether this technique can be applied to assess transatrial shunt flow in patients with atrial septal defect in a clinical setting. Methods In 46 consecutive patients with atrial septal defects, shunt flow was assessed during cardiac catheterization using the Fick method and by conventional 2-D quantitative transesophageal Doppler echocardiography. The averaged values for shunt flow obtained by both methods were used as a reference. Transesophageal 3-D color Doppler echocardiography was performed for analysis of the 3-D flow velocity field of transatrial shunt flow. Shunt volume was calculated by application of the Gauss theorem. Results We found a close correlation between shunt volume (L/min) obtained by either 3-D color Doppler echocardiography or the reference methods ( r = 0.981, P < .001). Using 3-D color Doppler data to predict the reference values, 95% confidence limits were -11.5 to +11.6%. Conclusions Shunt flow in patients with atrial septal defects can be assessed in a clinical setting by transesophageal 3-D color Doppler echocardiography.
