The objectives of this study were to determine whether three‐dimensional ultrasonography can provide more cardiac views than two‐dimensional ultrasonography and to develop a standard technique. Eighteen women, 16 to 26 weeks' gestation, were scanned with two‐dimensional ultrasonography for 10 minutes or less to obtain fetal heart views. Three‐dimensional ultrasonography was used (< or =10 minutes) to obtain up to 4 acquisitions of the fetal heart: 4‐chamber view, left parasagittal, transverse, and longitudinal nonstandard. Views were later extracted from saved volume data, comparing the yields of two‐ and three‐dimensional ultrasonography. The 4‐chamber view was obtained in 15 (93%) of 16 cases on both two‐ and three‐dimensional ultrasonography. On two‐dimensional ultrasonography, the left outflow tract was obtained in 68% of the cases; on three‐dimensional ultrasonography, the left outflow tract was obtained in 46% from the 4‐chamber view acquisition and in 100% from the left parasagittal acquisition. On two‐dimensional ultrasonography, the right outflow tract was obtained in 68% of the cases; on three‐dimensional ultrasonography, the right outflow tract was obtained in 86% from the 4‐chamber view acquisition and in 71% from the left parasagittal acquisition. Aortic and ductal arches were obtained in 12% and 18%, respectively, on two‐dimensional ultrasonography. On three‐dimensional ultrasonography the aortic and ductal arches were obtained in 66% and 86%, respectively, from the 4‐chamber view acquisition and in 57% and 71%, respectively, from the left parasagittal acquisition. Three‐dimensional ultrasonography permitted a greater number of cardiac views to be extracted from volume data than did two‐dimensional ultrasonography.
