OP12. 09: The value of the sagittal view of the ‘ductal arch plane’in the prenatal diagnosis and counseling of conotruncal anomalies using 4D ultrasonography Academic Article uri icon


  • Objectives Conotruncal anomalies represent one-fifth of all congenital heart defects (CHDs) detected in the fetus. However, the spatial relationship of the vascular connections is incorrectly diagnosed in about 20% of these cases. The sagittal view of the ductal arch is considered a standard sonographic view in fetal echocardiography, and can easily be visualized using four-dimensional (4D) ultrasonography. This study was designed to determine the value of this plane for the prenatal diagnosis of conotruncal anomalies. Methods We reviewed four-dimensional volume datasets, acquired with the spatiotemporal image correlation technique (STIC), from fetuses with and without confirmed conotruncal anomalies. The visualization rate of the sagittal view of the ductal arch was compared among groups using standardized multi-planar views which allowed the simultaneous …
