Stent migration is an uncommon complication of endovascular stenting procedures.It could cause serious cardiovascular complications.In this article, we describe an interesting case of acute heart failure as a result of stent embolization from the left common iliac vein into the right ventricle and how it was identified and managed.A patient underwent peripheral endovascular intention for may-thurner sysdrome (stenosis) with placement of a self-expanding nitinol protégé stent to the left iliac vein.6 months post procedure the patient was diagnosed with acute heart failure and pneumonia and was administered diuretics and antibiotics.Other symptoms included dyspnea and lower extremity edema.A transoesophageal echocardiogram revealed the stent straddling the tricuspid valve from the right atrium with the other end lodged in the trabeculation of the right ventricle with severe tricuspid regurgitation.A percutaneous endovascular approach with a 35- mm medtronic-covidien amplatzer gooseneck snare was initially attempted to retrieve the migrated stent.However, the snared proximal segment fractured, leaving behind 2 stent fragments.The patient was subsequently referred for surgical extraction via median sternotomy with use of cardiopulmonary bypass.During the operative procedure it was found the majority of the primary chords to the anterior and posterior leaflets ruptured.After successful stent extraction she underwent valve replacement with a non-mdt device.Her postoperative course was complicated by hemopericardium secondary to anticoagulation resulting in cardiac tamponade that was drained percutaneously, and small thromboembolic cerebellar stroke from atrial fibrillation.She was discharged to an inpatient rehabilitation facility and did well on 8-month follow-up.
