Inferior Vena Cava Filter Migrated to Left Ventricle.

Inferior vena cava (IVC) filters have been widely used to prevent pulmonary emboli in patients with venous thromboembolism. Here we report a rare case of complete pericardial tamponade with severe mitral and tricuspid valve regurgitation due to a fractured IVC filter. A 38-year-old male came to our emergency department with a 19-day history of progressive chest tightness. Chest x-ray revealed a tethering catheter fractured at the level of the junction of the superior vena cava and the right atrium. We performed open surgery and discovered that a steel wire had punctured the atrioventricular septum, the mitral valve, and finally the posterior wall of the left ventricle. The patient recovered quite well and was discharged after 1 week.
