      <Abstract>Persistent Left Superior Vena Cava (PLSVC) is an uncommon congenital anomaly; it has an incidence of 0.5% in the general population. A concurrent right superior vena cava anomaly with PLSVC is even rarer, with an incidence of 0.09%-0.13% in the general population. Patients with PLSVC are usually asymptomatic, and PLSVC is incidentally detected by Computed Tomography (CT) and catheter angiography, or during complicated surgical procedures, such as pacemaker implantation [1].&#13;
In this report, we present a case of an elderly patient with PSLSV and concurrent occurrence of absent right subclavian vein and Complete Atrioventricular Block (CAVB). In clinical settings, both a CAVB and an absent right subclavian vein are rarely encountered in PLSVC. Leadless pacemakers, an emerging technology, is an effective treatment option for patients with such vascular anomalies, including the present case.</Abstract>
