Very Late Iliac Venous Stent Migration Into the Right Ventricle With Tricuspid Valve Injury Five Years After Implantation: A Case Report.

Stent migration into the right heart chambers is an uncommon but potentially life-threatening complication of venous stenting. Most reported cases occur shortly after implantation. A 72-year-old man with prior left iliac vein stenting presented five years later with dyspnea and hemoptysis. Imaging revealed migration of the iliac stent into the right ventricle, in direct contact with the tricuspid valve apparatus. The patient underwent successful surgical removal on a beating heart, including neocordae implantation and annuloplasty ring placement. Postoperative recovery was uneventful. This case illustrates the potential for very late stent migration, emphasizes the risk of valvular damage, and underlines the importance of long-term surveillance following venous stent implantation.
