This study details a rare case of left isomerism with abnormal systemic venous connection, successfully treated with complete surgical repair. The findings highlight effective diagnostic and treatment strategies for this complex congenital heart defect.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Left isomerism, a rare congenital anomaly, presents complex cardiac malformations.
- Total anomalous systemic venous connection (TASVC) involves abnormal drainage of systemic veins.
Observation:
- A 7-year-old patient presented with absent inferior vena cava and other systemic veins abnormally connected to the left atrium.
- The condition included a hypoplastic right atrium, intact atrial septum, and pulmonary blood flow via a ventricular septal defect.
Findings:
- Diagnosis was confirmed using echocardiography, angiography, and computed tomography.
- Complete surgical repair was successfully performed, addressing the complex venous anomalies and intracardiac defects.
Implications:
- This case demonstrates the feasibility of successful surgical correction for complex left isomerism with TASVC.
- Effective diagnostic imaging and surgical planning are crucial for favorable outcomes in such pediatric cardiac cases.

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.

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...
