Right ventricular needle embolus in an injecting drug user: the need for early removal.

This case report describes an unusual cardiac complication in a 22 year old, female injecting drug user. The retention of two fractured injection needles at the site of intravenous injection in the groin, and the subsequent embolisation of one to the right ventricle, predisposed to recurrent local and systemic infections, and endocarditis. Two years later, the needle was completely embedded in the wall of the right ventricle and not suitable for transvenous removal. Removal of the retained and/or embolised needle at an earlier stage would have precluded these complications.
