Percutaneous Retrieval of a Migrated Iliac Vein Stent Traversing the Tricuspid Valve

Intracardiac stent migration is a rare but potentially life-threatening complication of venous interventions, often requiring surgical management.

A 38-year-old patient underwent left common iliac vein endovascular intervention with an 18 × 80-mm self-expanding venous stent and presented 1 day later with palpitations and dyspnea. Imaging demonstrated stent migration across the tricuspid valve, causing severe regurgitation and nonsustained ventricular tachycardia. The stent was successfully retrieved using a dual-snare technique via bilateral femoral access under general anesthesia with transesophageal echocardiographic guidance and surgical backup. Postretrieval imaging revealed only mild residual tricuspid regurgitation. The patient recovered uneventfully.

Venous stent migration into the tricuspid valve can be managed safely through a multidisciplinary, collaborative, transesophageal echocardiography-guided percutaneous approach, offering a minimally invasive alternative to surgery.

Percutaneous retrieval of migrated venous stents is feasible and safe when performed in a hybrid environment by an experienced interventional, surgical, and imaging team. Early transition to a dual-snare technique with deflectable sheaths should be considered when a single-snare attempt risks injury to the tricuspid apparatus.
