Corrected information:d3.Additional information: d10, g2, g4,g7, h2, h3, h6 & h10.Explant was reported due to vegetation and cerebral infarction.The investigation found probable endocarditis (clinical correlation would be required) with treatment effects.Vegetations were found on the inflow and outflow surface of all three leaflets.Intact and degenerating acute and chronic inflammatory cells, consistent with a treatment effect, were present.Focal disruption of cusp tissue by the vegetation was present in leaflet 2.A micro-calcification was present in a detached piece of thrombus from leaflet 1.Grams stains were negative for organisms.All three leaflets were fibrotically thickened.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed and the product met all specifications.The cause of the vegetation could not be conclusively determined.
