Manufacturer Narrative

Explant was reported due to thrombus.The investigation found that there was limited mobility of the leaflets.Thrombus was present in both the recessed pivot areas and on the sewing cuff.There were entrapped leukocytes within the thrombus, however no true inflammation or significant calcifications were present.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed and the product met all specifications at the time of commercialization.The thrombus present in the recessed pivot areas would limited the mobility of the leaflets.
