Summary
This summary is machine-generated.Persistent left superior vena cava (PLSVC) occurs in 6.5% of pediatric congenital heart surgery patients. Early diagnosis of PLSVC through echocardiography aids in managing potential complications.
Area Of Science
- Pediatric Cardiology
- Thoracic Surgery
- Medical Imaging
Background
- Persistent left superior vena cava (PLSVC) is a congenital anomaly where the left superior vena cava does not regress during embryonic development.
- Understanding the prevalence and associated cardiac defects of PLSVC is crucial for surgical planning and patient outcomes.
Purpose Of The Study
- To determine the frequency of PLSVC in children undergoing congenital heart surgery.
- To investigate the impact of PLSVC on surgical outcomes in this pediatric population.
Main Methods
- Retrospective analysis of 4,000 pediatric patients (under 16 years) who underwent congenital heart surgery between October 2021 and October 2024.
- Evaluation of PLSVC presence, drainage patterns, and association with other cardiac anomalies.
- Statistical analysis to assess the impact on surgical outcomes.
Main Results
- PLSVC was identified in 6.5% (260/4,000) of patients.
- The majority of PLSVC cases (92.3%) drained into the coronary sinus.
- PLSVC was frequently associated with heterotaxy syndrome, atrioventricular septal defects, and vascular ring anomalies.
Conclusions
- PLSVC is more common in specific congenital heart disease groups.
- Increased awareness during echocardiography can improve PLSVC diagnosis.
- Preoperative identification of PLSVC is vital for effective complication management.

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
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...
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...
The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
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.
