Purpose: The aim of this article is to report a rare case of unintended coil migration into the right (Rt) ventricle. Materials and Methods: A 36-year-old Brazilian female was referred to us for the evaluation of pelvic pain. Venous duplex ultrasound findings were consistent with incompetent venous systems of right lower extremity (RLE). The diagnosis of grade III pelvic varices was confirmed with ovarian venography, and bilateral ovarian vein coil embolization was performed. The procedure was complicated with unintended migration of a small coil into the Rt ventricle. Discussion: In cases where coil or foreign body migration into the Rt heart or pulmonary circulation has occurred, endovascular retrieval or a thoracotomy has been performed. In our case, the migrated coil was left in situ without any hemodynamic disturbances in the follow-up. Conclusions: Coil migration to the Rt ventricle can be conservatively managed depending upon the location and coil profile.
