On (b)(6) 2013, a 21mm trifecta valve was implanted in the patient's aortic position.In (b)(6)2018, the patient was admitted to the hospital with cardiac failure and leakage was confirmed by follow-up echocardiography.On (b)(6) 2018, the valve was explanted and replaced with a 21mm carpentier-edwards perimount magna ease valve.Upon explant of the trifecta valve, there were vertical tears on the right coronary cusp (rcc) and a left coronary cusp (lcc) from the respective stent post.Intima was slightly observed on the inflow side but it did not reach to each cusps and no pannus formation was noted.The patient is reported to be stable.

The 21mm trifecta valve was received in the product performance engineering lab in solution within a device return kit.The valve was grossly and microscopically examined.The sewing cuff was intact and contained blood/body fluids, white tissue, tan tissue and sutures.Leaflet 1 contained a tear along the base and continuing to the stent post shared with leaflet 2.Leaflet 2 contained a tear near the free edge that continued to the stent post shared by leaflet 1.A second tear at the base of leaflet 2 was noted that continued to the stent post shared with leaflet 3.The leaflets were mobile when manually manipulated.
