Key result
Cardiac implantable electronic devices were successfully placed via a persistent left superior vena cava using a wide loop technique in the right atrium to cross the tricuspid valve.
Why the study?
Persistent left superior vena cava is an uncommon congenital anomaly that makes lead placement technically challenging during left subclavian transvenous cardiac device implantation.
Population

Single-case success supports feasibility; hypothesis-generating and should not yet change practice.
Case Report (n=2)
The wide loop technique in the right atrium is a useful maneuver for crossing the tricuspid valve and affixing the right ventricular lead during CIED implantation in patients with persistent left superior vena cava.
Naqvi et al. (2020) conducted a case report in Persistent left superior vena cava requiring cardiac implantable electronic device (n=2). Cardiac implantable electronic device placement via persistent left superior vena cava was evaluated on Successful device implantation. Cardiac implantable electronic devices were successfully placed via a persistent left superior vena cava using a wide loop technique in the right atrium to cross the tricuspid valve.
