Abstract

RESTREPO, Gustavo; TRESPALACIOS, Erik; AHUMADA, Salim  and  TORO, Nancy. Persistent left superior vena cava. Rev. Colomb. Cardiol. [online]. 2014, vol.21, n.2, pp.115-118. ISSN 0120-5633.

Persistent left superior vena cava (PLSVC) is the most common variation of the thoracic venous system and it is frequently associated with other congenital defects. Its presence is usually detected during the central venous catheter insertion. An echocardiographic finding of a dilated coronary sinus is the most frequent indirect sign of PLSV presence. When this abnormal vessel drains into the left atria, a repair procedure is indicated. PLSVC course is usually benign, but when found, a search for an associated congenital cardiovascular defect is mandatory.
