Persistent left superior vena cava and its clinical implications: case report and literature review

Abstract

The persistent left superior vena cava venous anomaly is the most common congenital malformation of the thoracic venous system with an estimated prevalence of 0.3 to 0.5%. After dissection of a 30-week-old male fetus, was observed a persistent left superior vena cava that drained into the left atrium. Understanding this anomaly is crucial, given the widespread use of invasive cardiac and electrophysiological procedures.
