Persistent left superior vena cava: a blessing in disguise
Department of Cardiovascular Medicine, University of Toledo Medical Center, 3000 Arlington Avenue, Toledo, OH 43614, USA
Persistent left superior vena cava (SVC) is an uncommon condition, usually encountered during cannulation of the left subclavian vein. We describe a patient who required a cardiac device upgrade to cardiac resynchronization implantable cardioverter defibrillator for biventricular failure. The presence of a persistent left SVC proved to be a blessing in disguise in this patient as he had since developed total occlusion of the left subclavian-innominate system.
Key Words: Persistent left superior vena cava, Congenital cardiac anomalies, Cardiac resynchronization therapy
