Description
Summary:Superior vena cava (SVC) syndrome is a rare complication associated with transvenous cardiac implantable electronic devices that may present with a variety of manifestations. Various strategies such as transvenous lead extraction, anticoagulation, venoplasty, and stenting have been used to treat this condition, but the optimal management protocols have yet to be defined. Subcutaneous implantable cardioverter-defibrillator (ICD) (S-ICD) therapy can be an alternative option to a transvenous system for those who require future ICD surveillance. We present a case of lead-associated SVC syndrome where thoracic venous congestion due to SVC obstruction influenced preimplant S-ICD QRS vector screening. Following treatment of venous obstruction, QRS amplitude may change and patients who were not initially S-ICD candidates may later become eligible.
