2024年7月28日 · A left-sided superior vena cava (SVC) is the most common congenital venous anomaly in the chest, and in a minority of cases can result in a right-to-left shunt 3,4. A left-sided SVC is seen in 0.3-0.5% of the normal population and in …

In anatomy, a persistent left superior vena cava is the most common variation of the thoracic venous system. [1] [2] It is present in between 0.3% and 0.5% of the population, [3] [4] [5] and is an embryologic remnant that results from a failure to involute.

Persistent left superior vena cava (PLSVC) is a rare vascular anomaly that begins at the junction of the left subclavian and internal jugular veins, passes through the left side of the mediastinum adjacent to the arcus aorta. It mostly drains into the right atrium via the coronary sinus (CS).

Persistent Left Superior Vena Cava (PLSVC) creates a connection from the SVC to the coronary sinus. It is something we do not routinely see on echo but is always a great catch when we do see it! This week we will review the subclavian anatomy and blood flow of a PLSVC.

Persistent left superior vena cava (PLSVC) is the most common congenital malformation of thoracic venous return and is present in 0.3 to 0.5% of individuals in the general population. This heart specimen was dissected from a 35-yearold male cadaver whose cause of death was determined as non-cardiac.

Persistent left superior vena cava (LSVC) is the commonest congenital anomaly of the thoracic venous system. It is within the group of anomalous systemic venous return (ASVR) and the group is subdivided in cephalic, involving the superior vena cava (SVC) and caudal, involving the inferior vena cava (IVC) types.

This leaflet is to help you understand what a persistent left superior vena cava (PLSVC) is, what tests you may need and the implication of having been diagnosed with a persistent left superior vena cava for your baby and your family.

INTRODUCTION: Persistent left superior vena cava (PLSVC) is one of the common congenital anomalies of the thoracic venous system and usually accompanies other structural abnormalities such as: aortic coarctation, tetralogy of fallot, and transposition of the great vessels.

2022年11月29日 · Although an accessory left-sided superior vena cava is the most common malformation of the venous system, it occurs only rarely with an incidence of 0.3–0.5% in otherwise cardiac-healthy individuals. 1,2

2020年10月15日 · Persistent left superior vena cava (PLSVC) is the most common thoracic venous anomaly and may be a component of the complex cardiac pathologies. While it is often asymptomatic, it can lead to significant problems such as arrhythmias and cyanosis.
