Right atrial sensing for VDD pacing through a persistent left superior vena cava

Area of Science:

• Cardiology
• Medical Devices
• Electrophysiology

Background:

• Persistent left superior vena cava (PLSVC) is a rare congenital anomaly.
• Standard pacemaker lead implantation can be challenging in patients with PLSVC.

Observation:

• A case report of pacemaker implantation in a patient with PLSVC is presented.
• The VDD pacing mode was utilized for cardiac rhythm management.

Findings:

• A novel approach for pacing lead insertion through the PLSVC was successfully employed.
• A large retrograde lead course facilitated optimal positioning of sensing electrodes in the right atrium.

Implications:

• This technique offers a viable solution for pacemaker implantation in patients with PLSVC.
• Successful lead placement ensures effective cardiac pacing and monitoring.
