Key result
In a patient with persistent left superior vena cava and absent right superior vena cava, a dual-chamber pacemaker plan was successfully modified to a single-chamber atrial lead pacemaker due to challenging anatomy.

Rare venous anomalies may require pacing plan adaptation; leaves open optimal long-term strategies in persistent left SVC.
Case Report (n=1)
Persistent left superior vena cava with absent right superior vena cava can complicate pacemaker implantation, requiring anatomical adaptation such as single-chamber atrial pacing.
Sabzwari et al. (2020) conducted a case report in Tachy-brady syndrome with persistent left superior vena cava and absent right superior vena cava (n=1). Single-chamber atrial lead pacemaker implantation was evaluated on Successful pacemaker implantation. In a patient with persistent left superior vena cava and absent right superior vena cava, a dual-chamber pacemaker plan was successfully modified to a single-chamber atrial lead pacemaker due to challenging anatomy.
