HDlive Flow for the Diagnosis of Double Outlet Right Ventricle at 19 Weeks of Gestation

We present a case of double outlet right ventricle (DORV) diagnosed prenatally using HDlive Flow with spatiotemporal image correlation (STIC) at 19 weeks of gestation. Bilateral choroid plexus cysts were noted on routine second-trimester screening. Ventricular septal defect, a small pulmonary artery, and parallel arrangement of great arteries were identified using conventional fetal echocardiography and Radiant Flow. HDlive Flow clearly showed a large aorta and small pulmonary artery leaving the right ventricle in parallel. Moreover, abnormal running of the aortic arch and descending aorta was depicted spatially. The diagnosis of DORV was confirmed antenatally. HDlive Flow may be an adjunctive technology to conventional fetal echocardiography for the assessment of normal and abnormal cardiac structures of the fetus in utero .
