Fetal Ebstein Anomaly and Tricuspid Valve Dysplasia Registry

Ebstein Anomaly | Tricuspid Valve Dysplasia

Ebstein anomaly and tricuspid valve dysplasia (EA/TVD) are rare congenital tricuspid valve malformations that carry among the highest mortality of all congenital heart disease diagnosed in utero. Despite the high mortality associated with severe EA/TVD in the fetus, it has only been studied retrospectively. By prospectively enrolling a cohort across multiple centers, many questions may be answered in the perinatal period and beyond. The registry will allow us to understand perinatal and postnatal decision-making in this complex group of patients across centers.
