Narrow Escape: A Novel Approach to the Endovascular Treatment of Superior Vena Cava Syndrome Secondary to Pacemaker Leads with Excellent Long-term Outcomes.

ABSTRACT

Pacemaker or defibrillator placement is a common procedure done in more and more patients due to increased longevity and the prominence of cardiac disease. With more indications for cardiac implantable electrode devices, the devices themselves have evolved into more complex structures with more leads. The mechanical stress, risk of infection, and decreased blood flow through the superior vena cava (SVC) put patients at risk for SVC obstruction. Herein, we present a rare case of complete SVC obstruction secondary to fibrosis due to pacemaker leads which was treated with venoplasty and showed excellent long-term results. We also review the current literature on different approaches to treating SVC obstruction in this group of patients.
