Key result
A cardiac resynchronization therapy upgrade utilizing interventional coronary and radiological techniques successfully treated a patient with total subclavian vein occlusion caused by a previous pacemaker.
Why the study?
Transvenous pacemaker lead implantation can cause subclavian vein stenosis or occlusion, presenting difficulty for cardiac resynchronization therapy upgrade.

May support interventional CRT upgrade for subclavian vein obstruction; leaves open confirmation of safety and efficacy in larger studies.
BACKGROUND: Subclavian vein stenosis or occlusion may be caused by a transvenous pacemaker, which makes the reimplantation of a new pacemaker lead difficult. Transvenous pacemaker lead implantation-related subclavian vein occlusion may present difficulty with regard to cardiac resynchronization therapy (CRT) upgrade. CASE SUMMARY: We report the case of a 46-year-old man who was admitted with total subclavian vein occlusion caused by a permanent pacemaker that had been implanted 2 years previously. We successfully treated this patient with an upgrade to a CRT pacemaker by utilizing transferable interventional coronary and radiological techniques. The patient recovered uneventfully during the follow-up period. CONCLUSION: CRT upgrade is still a viable technique for the treatment of subclavian vein obstruction caused by previous pacemaker implantation.
