Event Description

On (b)(6) 2012, a 21mm trifecta valve was implanted.On (b)(6) 2017, the valve was explanted secondary to symptomatic calcification and high gradient.At the time of the implant the bypass time was 122 min and aortic x-clamp was 93 minutes.Additional information has been requested.

Manufacturer Narrative
|
The reported event of calcification was confirmed.Morphological and histopathological examination revealed calcifications in all three leaflets.Leaflet 1 contained fibrous thickening, all three leaflets contained circumferential fibrous pannus ingrowth which narrowed the inflow diameter, and leaflet 1 was folded in on itself.Leaflet 3 had been excised prior to analysis.No acute inflammation was present in the valve.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed.The cause of the reported event remains unknown; however, high gradient is consistent with calcified leaflets.
