Abstract

Objective

To assess the success rates of five fetal cardiac views using HDlive Flow (Silhouette) with spatiotemporal image correlation (STIC) in the second and third trimesters of pregnancy, and to verify the feasibility of obtaining five cardiac views by volumes.

Methods

One hundred and eighteen normal fetuses at 18–21 and 28–31 weeks of gestation were studied using HDlive Flow (Silhouette) with STIC to assess the success rates of five fetal cardiac views (frontal, spatial three-vessel, panoramic, posterior, and right lateral views). Target structures in each cardiac view were evaluated. “Good” was assigned when all structures were noted, “Fair” when only one structure was missed, and “Poor” when two and more structures could not been detected.

Results

There were no significant differences in success rates of each cardiac view between 18–21 and 28–31 weeks of gestation. The rate of “Good” with a spatial three-vessel view was significantly higher than that with other cardiac views at 18–21 and 28–31 weeks, respectively (P < 0.05).

Conclusion

Five cardiac views using HDlive Flow (Silhouette) with STIC may become an adjunctive and useful tool in fetal cardiac examination.
