A 68-year-old female presents with AV block after mitral repair surgery. Persistent left superior vena cava (PLSVC) was diagnosed during double chamber pacemaker implantation. PLSVC has a prevalence of 0.3-0.5% and may render cardiopulmonary bypass and device implantation more challenging. Nevertheless, evidence suggests it does not influence long-term follow-up.
