Unusual finding of cor triatriatum in a newborn with hypoplastic left heart syndrome

Area of Science:

• Cardiology
• Congenital Heart Disease
• Pediatric Cardiology

Background:

• Cor triatriatum is a rare congenital heart anomaly characterized by the partitioning of the left atrium.
• It typically results in obstruction of blood flow from the pulmonary veins to the mitral valve.
• While often isolated, it can coexist with other cardiac defects.

Observation:

• This report describes a rare case in a newborn diagnosed with hypoplastic left heart syndrome.
• The newborn also presented with the unusual finding of cor triatriatum sinistrum.
• This specific combination has not been previously documented in medical literature.

Findings:

• The study identifies a co-occurrence of two significant congenital heart conditions: hypoplastic left heart syndrome and cor triatriatum sinistrum.
• This case highlights the potential for rare anatomical variations to present together in complex congenital heart disease.
• The presence of cor triatriatum sinistrum in this context adds a unique dimension to the known spectrum of hypoplastic left heart syndrome.

Implications:

• This case expands the understanding of congenital heart defect associations.
• It may prompt further investigation into the embryological mechanisms underlying combined cardiac anomalies.
• Clinical awareness of this rare association is important for accurate diagnosis and management of affected newborns.
