Slittable sheath supported right ventricular pacing lead implantation in persistent left superior vena cava with absent right superior vena cava: A case report

Persistent left superior vena cava (PLSVC) is the most common variant of systemic venous drainage. In the absence of the right superior vena cava (RSVC), implantation of a right ventricular pacing lead may be challenging. Therefore specific implantation techniques and experiences in PLSVC are worth reporting.
