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).
