Dual, nonconfluent infradiaphragmatic total anomalous pulmonary venous return (TAPVR) is exceptionally rare in neonates. Advanced imaging is crucial for diagnosing and planning surgical repair of complex venous anomalies.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Neonatal Surgery
Background:
- Infradiaphragmatic total anomalous pulmonary venous return (TAPVR) is a rare congenital heart defect.
- Dual, nonconfluent pulmonary venous pathways represent an exceptionally uncommon subtype, complicating diagnosis and surgical planning in neonates.

Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

Veins of the Abdomen and Pelvis
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...
