Amplatzer vascular plug closure of a subclavian arteriovenous fistula associated with implantable cardioverter‐defibrillator implantation

Abstract

Subclavian arteriovenous fistula (AVF) is a rare complication of implantable cardioverter-defibrillator (ICD) implantation. This report illustrates the case of a subclavian AVF after ICD implantation in a patient with nonischemic cardiomyopathy and the successful closure of this AVF using an Amplatzer vascular occlusion plug. Given the increasing number of ICD implantations, physicians should be made aware of this uncommon complication. In addition, as more percutaneous endovascular techniques are developed to treat peripheral vascular and structural heart disease, iatrogenic AVFs may occur more frequently. The Amplatzer vascular plug should be considered as a potential treatment strategy for AVFs alongside other endovascular and surgical techniques.
