It was reported that an optease vena cava filter was placed in the patient in 2006 and ¿after a while¿, it migrated to the right ventricle of the heart which was found in 2011.There were no patient injuries.The customer would like to know how long cava filter can maintain its integrity.Multiple attempts to gather additional information and contact the customer has been unsuccessful.The product was not returned for analysis.Additionally, as the sterile lot number was not available, device history record review could not be performed. the optease vena cava filter is indicated for use in the prevention of recurrent pulmonary embolism (pe) via percutaneous placement in the vena cava for patients in which anticoagulants are contraindicated, anticoagulant therapy for thromboembolic disease has failed, emergency treatment following massive pulmonary embolism where anticipated benefits of conventional therapy are reduced or for chronic, recurrent pulmonary embolism where anticoagulant therapy has failed, or is contraindicated.The purpose of a vena cava filter is to catch thrombus from the lower extremities as it travels along normal blood flow patterns up towards the heart.Retrieval of the optease vena cava filter is indicated up to 23 days post implantation.Following this period of time, it is intended to be permanently implanted.Without images or procedural films for review, the reported filter migration could not be confirmed and the exact cause could not be determined.Giving the limited information available at this time, clinical factor contributing to the migration could not be determined.Inferior vena cava (ivc) filter migration is a known potential adverse event associated with all ivc filter implants and is listed in the instruction for use (ifu) as such.Possible causes for filter migration includes mega cava, wire entrapment during central venous catheter placement, ¿sail¿ effect (cranial migration) of large clot burden within the filter, mechanical device failure, and operator error.Physiologic causes of migration may result from temporary dysmorphism of the inferior vena cava including bending, coughing or valsalva maneuvers resulting in dislodgment of the filter.Some studies suggest that strenuous physical activity and increased intra-abdominal pressure can lead to migration of ivc filters.Given the limited information available for review at this time, there is nothing to suggest that the reported event is related to the design and/or manufacturing process of the device; therefore no corrective action will be taken.Should additional information become available, the file will be updated accordingly.
