A great majority of cardiac implantable electronic device (CIED) implantation procedures require the transvenous introduction of leads into the heart. Thus, any developmental anomalies or anatomical variations of these veins may affect the course of the procedure. This paper presents a case of double superior vena cava in combination with brachiocephalic vein (innominate vein) agenesis. The asymptomatic nature of this systemic venous anomaly made it difficult to detect before the CIED implantation procedure.
