VERGARA S, Ismael; FRANGINI S, Patricia and BARRERO V, Raúl. Placement of a biventricular resynchronization device in a patient with a persistent left superior vena cava: Report of one case. Rev. méd. Chile [online]. 2012, vol.140, n.1, pp. 84-87. ISSN 0034-9887. doi: 10.4067/S0034-98872012000100012.
Persistent left superior vena cava is the most common venous congenital malformation and is usually asymptomatic. Its presence could increase the difficulty for transvenous lead implantation. We report a 71-year-old woman with an idiopathic dilated cardiomyopathy, atrial fibrillation and heart failure that required biventri-cular resynchronization therapy. During the placement of the device a persistent left superior vena cava was detected. The device was placed without problems and the patient had a satisfactory postoperative evolution.
