Passive fixation j-shaped atrial lead implantation technique using left-sided approach in a patient with persistent left superior vena cava

Persistent left superior vena cava may be found in 0.3-0.47% of cases during endocardial pacemaker implantation with left-sided approach. This venous anomaly can complicate lead placement during implantation. Active fixation leads are usually used. We described a new technique for passive fixation J-shaped atrial lead implantation via persistent left superior vena cava using left-sided approach. Stable position, pacing and sensing parameters were unchanged after 12 months of follow-up.
