Ebstein anomaly and Trisomy 21: A rare association

Area of Science:

• Pediatric Cardiology
• Medical Genetics
• Neonatology

Background:

• Trisomy 21 (Down syndrome) is associated with congenital heart defects.
• Ebstein anomaly is a rare congenital heart condition affecting the tricuspid valve.
• Acquired pulmonary vein stenosis is an uncommon complication, particularly in neonates.

Observation:

• A neonate presented with a rare combination of congenital anomalies.
• The patient was diagnosed with Trisomy 21, Ebstein anomaly, and a ventricular septal defect.
• Acquired pulmonary vein stenosis was also identified during routine neonatal examination.

Findings:

• The case highlights the coexistence of multiple, uncommon cardiac and genetic conditions in a single patient.
• Diagnosis was established through standard neonatal screening protocols.
• This rare combination presents unique diagnostic and management challenges.

Implications:

• This case underscores the need for vigilant cardiac screening in neonates with Trisomy 21.
• It emphasizes the potential for acquired complications like pulmonary vein stenosis in complex congenital heart disease.
• Further research into the pathogenesis and management of such rare combinations is warranted.
