ABSTRACT

Introduction: the persistence of the left superior vena cava (PLSVC) has a prevalence of 0.21% in the general population. Case presentation: 67-year-old male diagnosed with third-degree AV block, requiring pacemaker placement. However, due to the absence of a right superior vena cava, corroborated by CT angiography, a definitive pacemaker was placed through a persistent left superior vena cava. Conclusion: the persistence of the left superior vena cava (PLSVC) is the most common thoracic venous anomaly. It can cause a number of clinically significant symptoms, even in a heart with normal anatomy. Pacemaker placement makes electrode fixation difficult due to tortuous travel.
