Developments in endovascular therapies have made stenting a common practice in the treatment of peripheral vascular diseases, including venous disorders such as May-Thurner syndrome. The placement of a stent in the venous system carries the risk of stent migration which although small occurs with a 3% incidence rate and can be life-threatening given the risk of pulmonary infarction, tricuspid regurgitation, and right-sided heart failure. Herein we report a case of stent embolization from the common iliac vein into the right side of the heart causing tricuspid regurgitation. After the failure of percutaneous approach to retrieve the stent, it was successfully removed using a minimally invasive right thoracotomy approach along with repair of the tricuspid valve.
