Venoplasty of innominate bridge during implantation of single-chamber ICD in a patient with a persistent left-sided superior vena cava.

摘要

The persistent left-sided superior vena cava (PLSVC) is a common congenital abnormality, occurring in approximately 1% of patients. The presence of a PLSVC can complicate the implantation of a pacemaker or an automatic implantable cardioverter-defibrillator (AICD). In this case, we report a procedure, venoplasty of an innominate branch, to facilitate implantation of a right ventricular lead in a single-chamber AICD. This approach could potentially reduce procedure and fluoroscopy time in other similar cases.
