Left subclavian approach for ablation of persistent left superior vena cava in a patient with cardiac resynchronization therapy: a case report

Persistent left superior vena cava (PLSVC) causes arrhythmogenicity in atrial fibrillation (AF). However, in patients with cardiac resynchronization therapy (CRT), PLSVC ablation through the coronary sinus (CS) risks left ventricular (LV) lead dislodgement.
