We present the case of a 64-year-old male with complete atrioventricular block and unsuccessful traditional pacemaker lead implantation. Angiography confirmed a persistent left superior vena cava and atresia of the right vena cava draining into a dilated coronary vein. Subsequently, a leadless pacemaker was successfully implanted in the septal wall of the right ventricle, achieving optimal sensing and threshold values. This case highlights the challenges of anatomical anomalies in pacemaker implantation and the successful utilization of leadless pacemakers as an alternative. Awareness of such variations is crucial for decision-making and improved patient outcomes.
