Transvenous retrieval of a Greenfield filter lodged in the tricuspid valve.

A 77-year-old man had an inferior vena cava Greenfield filter placed for bilateral deep venous thrombosis acquired during a complicated hospitalization for a hip fracture. The filter migrated and lodged at the level of the tricuspid valve. We describe a transvenous retrieval approach which is safer and performed under more controlled technique than previously reported.
