Total anomalous systemic and pulmonary venous connection.

Area of Science:

• Cardiology
• Congenital Heart Disease
• Pediatric Cardiac Surgery

Background:

• Total anomalous venous connection (TAVC) is a rare congenital cardiac anomaly involving abnormal drainage of systemic and pulmonary veins.
• Accurate preoperative diagnosis is crucial for effective management of TAVC.
• Partial diagnosis can complicate surgical planning and postoperative care.

Observation:

• A 16-month-old boy with a partially diagnosed TAVC was managed.
• The systemic venous anomaly component was missed during initial preoperative evaluation.
• The child was monitored postoperatively.

Findings:

• The patient demonstrated a positive clinical course following management.
• Pulmonary artery pressure remained within normal limits during follow-up.
• The undetected systemic venous anomaly did not impede recovery.

Implications:

• This case underscores the challenges in diagnosing complex congenital heart anomalies.
• It suggests that successful management is possible even with incomplete preoperative diagnosis.
• Further research into advanced diagnostic techniques for TAVC is warranted.
