Abstract:

Objective: To assess STIC's contribution to the completion of the fetal cardiac examination during a standard abnormality scan. Methods: This is a longitudinal observational study at a single center. One skilled feto-maternal specialist conducted all of the scans. 8750 patients had routine anomaly scan including fetal heart examination according to ISUOG practice guidelines. Scan time was kept to the time frame allotted to routine anomaly scan. Only when the examiner was unable to complete the list recommended by ISUOG (ISUOG practice recommendations), which includes demonstration of, was the STIC technique, both conventional and electronic probes, employment of Situs and general aspect, atrial chambers, ventricular chambers and atrioventricular junction and valves. For the conventional STIC we employed a multiplanar approach, tomographic ultrasound imaging (TUI) and rendering approach. For electronic STIC, in addition to rapid acquisition of the volume we have used Biplane and sonoVCAD. Results: During the study time, 10750 patients were seen for routine anomaly scan52 participants were identified as having congenital heart abnormalities during the investigation. The total number of fetal malformations diagnosed during the time of the study was 350 which mean cardiac anomalies constituted (4%) of all fetal malformation in this study. In 1312 patient (15%) of the total number of patientsthe examiner could not obtain the full images required as per ISUOG protocol. Accordingly both conventional and electronic STIC was used in this group, depending on the condition. In all these patients the obstetrician was able to complete the examination. STIC was also applied to patients where a cardiac anomaly was suspected. More information with regards to these abnormal cases was found in 10% of the cases. Conclusion: In this study, we have demonstrated that the STIC technique enables us to collect a volume of sufficient quality, enabling us to complete the cardiac assessment, lower the amount of cases sent to fetal cardiologists, and, ultimately, lessen patient concern. Although STIC did not affect our incidence of cardiac abnormality detection, it did contribute more information to the diagnosis, which aided in our early counseling.
