Technical Tips and Efficacy of Leadless Pacemaker Implantation in a Patient With Isolated Persistent Left Superior Vena Cava

Abstract

Isolated persistent left superior vena cava (PLSVC) provides limited access during transvenous pacemaker implantation. We present a case of implantation of a leadless pacemaker for atrioventricular block with isolated PLSVC. A leadless pacemaker is an alternative strategy to a transvenous pacemaker; however, some technical tips are required: (1) the prevention of the mis-insertion in the dilated coronary sinus and (2) the pre-assessment of the anatomy of the right atrium and ventricle.
