Persistent Left Superior Vena Cava (PLSVC) is a rare congenital vascular anomaly (incidence of 0.3-0.5% of the general population) which being mostly asymptomatic in its presentation, is usually detected incidentally. There are many practical clinical implications associated with it including arrhythmias. We report a rare case of PLSVC with absent Right Superior Vena Cava (RSVC) (isolated PLSVC), in a 55-year-old lady who had complete heart block followed by sepsis and was diagnosed to have this condition during the permanent cardiac pacemaker implantation and central venous catheter insertion showing an abnormal path of the catheter/pacing leads. The authors also give an insight into its clinical relevance.
