Venous Obstruction in Cardiac Rhythm Device Therapy.

PURPOSE OF REVIEW: A variety of complex vascular pathologies arise following the implantation of electronic cardiac devices. Pacemaker and defibrillator lead insertion may cause proximal venous obstruction, resulting in symptomatic venous congestion and the compromise of potential future access sites for cardiac rhythm lead management. RECENT
FINDINGS: Various innovative techniques to recanalize the vein and establish alternate venous access have been pioneered over the past few years. A collaborative team of electrophysiologists and vascular specialists strategically integrate the patient's vascular disease into the planning of electrophysiology procedures. When vascular complications occur after device implantation, the same team effectively manages both the resulting vascular sequelae and related cardiac rhythm device challenges. This review will outline the various vascular challenges related to device therapy and offer an effective strategy for their management.
