Can a coronary sinus delivery system facilitate ICD lead implantation via persistent left superior vena cava?
Using a coronary sinus delivery system may facilitate ICD lead implantation in patients with persistent left superior vena cava, avoiding the need for complex stylet manoeuvring.
Persistent left superior vena cava (PLSVC) is a benign vascular anomaly that complicates pacemaker or implantable cardioverter defibrillator (ICD) lead implantation. Thus far, right ventricular lead implantation via PLSVC has been mostly accomplished by forming a U-shaped stylet, necessitating considerable manoeuvring depending on the heart size and geometry. In this article we report a technique of ICD lead implantation via PLSVC, using a coronary sinus delivery system as used today in cardiac resynchronization therapy.
