Persistent left superior vena cava (LSVC) in children with congenital heart disease increases mortality risk after cardiac surgery. Early diagnosis and recognition of associated anomalies are crucial for better outcomes.
Area of Science:
- Cardiology
- Pediatric Surgery
- Medical Imaging
Background:
- Persistent left superior vena cava (LSVC) is a common finding in congenital cardiac malformations.
- Understanding its impact on surgical outcomes is vital for pediatric cardiac patients.
Purpose of the Study:
- To analyze the diagnostic timing of persistent LSVC and associated coronary sinus anomalies.
- To evaluate the impact of persistent LSVC on morbidity and mortality in children undergoing cardiac surgery.
Main Methods:
- Retrospective analysis of 371 children with congenital heart disease undergoing cardiac surgery on bypass.
- Echocardiography was used for pre-operative diagnosis of persistent LSVC.
Main Results:
- Persistent LSVC was present in 12.7% of patients, with 83% diagnosed pre-operatively.
- Complications included left ventricular inflow obstruction (6.4%) and coronary sinus anomalies (17%).
- Mortality was significantly higher in patients with persistent LSVC (10.6% vs. 2.5%).
Conclusions:
- Persistent LSVC in congenital heart disease is associated with increased mortality after cardiopulmonary bypass.
- Pre-operative recognition of persistent LSVC and its anomalies is essential to prevent surgical complications.

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 middle...
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.
The...
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...

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
