Background: There have been some reports on prenatal diagnosis of a prominent eustachian valve, which can mimic a cardiac tumor in the right atrium. However, there has been no report on the sibling occurrence of persistent eustachian valves. Here, we present two fetuses (brothers) with a prominent eustachian valve in one family, diagnosed prenatally with fetal echocardiography and HDlive. Case description: In the first fetus (older brother), fetal echocardiography with second-trimester fetal screening showed a mobile, elongated, solid tumor (2.9 mm) at the base of the right atrium at 19 weeks and 3 days of gestation. The neonatal echocardiographic diagnosis was persistent eustachian valve. In the second fetus (younger brother), fetal echocardiography with third-trimester fetal screening showed a mobile, round, solid tumor (3.4 × 2.5 mm) at the base of the right atrium at 29 weeks and 4 days of gestation. HDlive clearly demonstrated a round tumor vibrating left and right, which was synchronized with systole and diastole, near the inferior vena cava. The neonatal echocardiographic diagnosis was persistent eustachian valve. Conclusion: This is the first report on two fetuses (brothers) with a prominent eustachian valve in one family. HDlive facilitates visualization of three-dimensional fetal intracardiac structures, such as a prominent eustachian valve.
