Truncus arteriosus communis. Unusual case associated with transposition

Area of Science:

• Pediatric Cardiology
• Congenital Heart Disease
• Cardiac Anatomy

Background:

• Truncus arteriosus communis is a complex congenital heart defect where a single great artery arises from the heart.
• Anatomical variations in the origin and spatial relationship of the great arteries can occur in truncus arteriosus communis.
• Understanding these variations is crucial for diagnosis and surgical planning.

Observation:

• A pediatric case of truncus arteriosus communis is described with a unique posterior origin of the pulmonary trunk.
• This specific arterial arrangement is atypical for truncus arteriosus communis.
• The spatial orientation of the great arteries in this case resembles that observed in transposition of the great vessels.

Findings:

• The posterior origin of the pulmonary trunk represents an unusual anatomical variant within the spectrum of truncus arteriosus communis.
• The observed spatial relationship between the great arteries presents diagnostic challenges and necessitates careful consideration.
• This anomaly highlights the diversity of complex congenital heart malformations.

Implications:

• Accurate terminology is essential for precise communication among clinicians and researchers studying complex congenital heart anomalies.
• This case underscores the importance of detailed anatomical assessment in pediatric cardiology.
• Further research into rare variants of truncus arteriosus communis may improve understanding and treatment strategies.
