Triple outlet right ventricle: a previously unknown cardiac malformation

Area of Science:

• Pediatric Cardiology
• Congenital Heart Disease
• Cardiac Surgery

Background:

• The "Tritruncal Heart" is an extremely rare congenital anomaly characterized by three distinct outflow tracts from the right ventricle.
• Understanding the embryology and anatomical variations of outflow tract development is crucial for diagnosing and managing complex congenital heart diseases.

Observation:

• This report presents a case of an infant diagnosed with a Tritruncal Heart.
• The infant's cardiac anatomy, diagnostic process, and surgical interventions are meticulously described.

Findings:

• The study reviews the two previously documented cases of Tritruncal Heart to contextualize the current case.
• Detailed anatomical description, diagnostic imaging findings, and surgical management strategies are presented for the infant case.

Implications:

• This case contributes to the limited literature on Tritruncal Heart, enhancing understanding of this rare condition.
• The discussion of embryologic implications may offer insights into the developmental pathways leading to complex outflow tract anomalies.
• Effective surgical management and long-term outcomes for such rare cardiac malformations remain critical areas for further investigation.
