Excerpt
Persistent left superior vena cava (PLSVC) is the most common thoracic vein anatomical variation with a reported prevalence of 0.3 % in the general population and up to ten times higher in patients with other congenital cardiovascular abnormalities [
1]. In almost 90 % of cases both SVCs are present, while in 30 % of cases a bridging innominate vein exists allowing communication between the right- and left-side veins [
2]. Generally, PLSVC drains into right atrium via the coronary sinus; as a result the latter becomes significantly dilated and can easily be appreciated with transthoracic echocardiography as a circular echo-free structure in the left posterior atrioventricular groove. However, in most cases this constitutes an incidental finding complicating procedures involving central vein cannulation or insertion of pacing wires/leads. …
