Terapia de resincronización cardiaca en paciente con vena cava superior izquierda persistente. Caso clínico.

Resumen

PLACEMENT OF A  BIVENTRICULAR RESYNCHRONIZATION DEVICE IN A PATIENT WITH  A PERSISTENT LEFT SUPERIOR VENA CAVA. REPORT OF ONE CASE

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 years old woman with an idiopathic dilated cardiomyopathy, atrial fibrillation and heart failure  that required biventricular 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.
