  • Title: Persistent Left Superior Vena Cava with the Absence of the Right Superior Vena Cava and Atrial Appendage: Complex Pacemaker Implantation in a Patient Presenting with a Rare Vascular Anomaly.

    Journal: Intern Med; 2024 May 15; 63(10):1373-1376. PubMed ID: 37743512.
    Abstract:
    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.
