Objective. The objective of our paper is to show that the spatio-temporal image correlation (STIC) and tomographic ultrasound imaging (TUI) is very convenient and helpful for the fetal screening of complex congenital heart defects (CHD). Methods. Ultrasound examinations were performed using a Voluson 730 EXPERT or PRO system (GE Medical system, Kretztechnik, Zipf, Austria), and the transabdominal probe (RAB 4-8 MHz or 1-5 MHz) was used to acquire the STIC volumes. Various complex CHD including heterotaxia, ventricular septal defect (VSD), atrio-ventricular septal defect (AVSD), tetralogy of fallot (TOF), transposition of great artery (TGA), hypoplastic left heart syndrome (HLHS) were examined between 20 weeks and 35 weeks. After routine cardiac screening and examination by two-dimensional ultrasound, three- and four-dimensional ultrasound were performed by gray-scaled and color flow mapping. After the examination detailed analysis of CHD were performed by STIC and TUI. Results. In the case of heterotaxia, STIC and TUI was useful for the detection of stomach and cardiac apex in the different slices. In the case of VSD and AVSD, they were useful for the exact determination of septal defect location. In the cases of TOF, TGA and HLHS, they were helpful for observation of outflow tract and exact diagnosis. Conclusion. In the screening of complex CHD including heterotaxia, VSD, AVSD, TOF, TGA and HLHS, STIC is very useful and powerful tool.
