Operative correction of cor triatriatum sinister with systemic venous return anomaly (inferior vena cava-left atrium)

Area of Science:

• Cardiology
• Congenital Heart Disease
• Cardiac Surgery

Background:

• Cor triatriatum sinister is a rare congenital cardiac anomaly characterized by a fibromuscular membrane within the left atrium.
• This anatomical abnormality partitions the left atrium into proximal and distal chambers.
• It commonly coexists with persistent left superior vena cava, but anomalous systemic venous return is infrequent.

Observation:

• A patient presented with cor triatriatum sinister.
• The patient also exhibited an unusual anomalous systemic venous return.
• This combination represents a rare clinical presentation.

Findings:

• Successful surgical intervention was performed for a patient with cor triatriatum sinister.
• The treatment addressed both the primary anomaly and the coexisting unusual systemic venous return.
• This case highlights the successful management of a complex cardiac defect.

Implications:

• This case demonstrates the feasibility of surgical correction for complex cor triatriatum sinister with anomalous venous return.
• It expands the understanding of surgical possibilities for rare congenital heart defects.
• Successful management offers hope for patients with similar rare cardiac anomalies.
