Figure 1.
(A) A Plain chest radiograph of the patient who received an implantable cardioverter defibrillator. A dual-coil defibrillator lead was implanted through the superior vena cava (SVC), and the SVC coil was contiguous to the lateral wall of the SVC. Electrical isolation of the SVC failed in the first ablation session.
(B) A plain chest radiograph of the patient who received a dual-chamber permanent pacemaker. The proximal electrode of the atrial lead (Stelid BJ45D, ELA Medical, Montrouge, France) was positioned 70 mm from the distal tip, and the proximal electrode corresponded with the level of the SVC isolation (yellow arrow).
