Key result
Single-lead pacemaker via PLSVC maintains effective pacing at 2 years despite absent RSVC.
Why the study?
Persistent left superior vena cava with absence of the right superior vena cava is a rare anomaly that complicates pacemaker implantation due to anatomical challenges.

Highlights the anatomical complexities and special considerations required for pacemaker lead placement in patients with isolated PLSVC and absent atrial appendage.
Feasibility shown for pacing via persistent left SVC in absent right SVC; leaves open safety, efficacy, and generalizability in larger cohorts.
A persistent left superior vena cava (PLSVC) is a commonly observed anatomical anomaly that is frequently detected incidentally via computed tomography (CT) imaging. However, the occurrence of a PLSVC with a right superior vena cava (RSVC) defect, also known as "isolated PLSVC," is a much rarer anomaly. This peculiar malformation can lead to sinoatrial dysfunction, thus necessitating pacemaker implantation, which requires delicate manipulation due to various anatomical complexities. We herein present a case of a sick sinus syndrome with this rare anomaly, which required special consideration when performing pacemaker lead placement.

Hata et al. (2023) conducted a case report in Sick sinus syndrome with isolated persistent left superior vena cava (n=1). Single-lead pacemaker implantation via PLSVC was evaluated on Successful pacemaker implantation and symptom resolution. Single-lead pacemaker implantation via a persistent left superior vena cava was successfully performed in a patient with sick sinus syndrome and absent right superior vena cava, maintaining effective pacing at 2 years.
