What this trial studies

This registry aims to collect data on fetuses diagnosed with Ebstein anomaly and tricuspid valve dysplasia, which are serious congenital heart defects. By enrolling mothers of affected fetuses across multiple centers, the study seeks to gather prospective information on perinatal and postnatal decision-making. The goal is to better understand the outcomes and management strategies for these complex cases, which have historically been studied retrospectively. This observational approach will provide valuable insights into the care of these patients.

Who should consider this trial

Good fit: Ideal candidates include mothers of fetuses diagnosed with Ebstein anomaly or tricuspid valve dysplasia at any gestational age.

Not a fit: Patients whose fetuses have EA/TVD in the context of abnormal segmental anatomy or other significant congenital heart defects may not benefit from this study.

Why it matters

Potential benefit: If successful, this registry could improve understanding and management of fetal Ebstein anomaly and tricuspid valve dysplasia, potentially leading to better outcomes for affected infants.

How similar studies have performed: While there have been retrospective studies on EA/TVD, this prospective registry approach is novel and aims to fill gaps in existing knowledge.
