Superior Vena Cava Syndrome Caused by Pacemaker Leads

Superior vena cava syndrome is one of the rare adverse events associated with pacemaker leads. We describe a 47-year-old woman with a pacemaker implanted 10 years earlier who presented to us with superior vena cava syndrome managed surgically. We report the presentation, diagnosis, and treatment of this patient and the causes and management options of superior vena cava obstruction associated with pacemaker leads.
