Key result
HDlive Flow and Silhouette delineate isolated fetal pericardial effusion resolving spontaneously by ~25 weeks gestation.
Case Report (n=1)
No
HDlive Flow and HDlive Silhouette ultrasound modes can clearly delineate the spatial relationship between isolated fetal pericardial effusion and the fetal heart in utero.
Isolated fetal pericardial effusions may resolve spontaneously; leaves open the clinical utility of HDlive modes beyond single cases.
groove) (Fig. 1).Radiant flow revealed no flow inside the cyst (Fig. 2).HDlive Flow and HDlive Silhouette (Voluson E10 BT21, GE Healthcare, Zipf, Austria) clearly depicted a spatial relationship between a tadpole-shaped echo-free space and the fetal heart (Fig. 3).The cyst disappeared at 24 weeks and 5 days of gestation.

Hata et al. (2023) conducted a case report in Isolated fetal pericardial effusion (IFPE) (n=1). HDlive Flow with spatiotemporal image correlation (STIC) and HDlive Silhouette was evaluated on Spatial depiction and clinical resolution of isolated fetal pericardial effusion. HDlive Flow and HDlive Silhouette clearly depicted a 5.6 mm isolated fetal pericardial effusion at 17 weeks and 4 days of gestation, which resolved spontaneously at 24 weeks and 5 days.
