Manufacturer Narrative
|
An event of explant due to stenosis was reported.The results of the investigation are inconclusive since the device was not returned for analysis.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.Based on the information received, the cause of the reported incident could not be conclusively determined.Per the site a smaller, 23mm, valve was implanted.

Event Description
|
On (b)(6) 2010, a 25mm trifecta valve was implanted.On (b)(6) 2019, the device was explanted due to stenosis and structural valve deterioration.The device was exchanged for a 23mm medtronic avalus valve.No patient consequences were reported.(clinical study patient id: (b)(6)).

7 october 2019 jl: additional information was received on 1 october 2019.The patient had a history of severe aortic insufficiency.On (b)(6) 2019, the patient was hospitalized for heart failure and acute pulmonary edema.On (b)(6) 2019, the trifecta valve was explanted and exchanged with a competitor's edwards valve.However, the patient passed away during the re-operation procedure.On (b)(6) 2010, a 25mm trifecta valve was implanted.On (b)(6) 2019, the device was explanted due to stenosis and structural valve deterioration.The device was exchanged for a 23mm medtronic avalus valve.No patient consequences were reported.(clinical study patient id: (b)(6) (b)(4)).

Event Description
|
On (b)(6) 2010, a 25mm trifecta valve was implanted.On (b)(6) 2019, the patient was hospitalized for severe aortic insufficiency likely secondary to endocarditis and atrial fibrillation with quick ventricular response.On (b)(6) 2019, the trifecta valve was explanted and exchanged with a competitor's carpentier edwards valve, which was successfully implanted.The issue was resolved with sequelae of progressive cardiac insufficiency.Abbott received additional information that on 9 july 2019, the patient was hospitalized for heart failure and acute pulmonary edema.On (b)(6) 2019, the patient underwent a second valve exchange to a medtronic avalus and died during this procedure.(clinical study patient id: (b)(6)).

Manufacturer Narrative
|
Explant was reported due to aortic insufficiency, likely secondary to endocarditis, and atrial fibrillation.The investigation found that there was circumferential fibrous pannus ingrowth on both the inflow and outflow surfaces, which narrowed the inflow diameter.All three leaflets were fibrotically thickened.Leaflet 2 contained a fold which caused incomplete coaptation.Calcifications were present of leaflet 2 and 3.Degenerative changes were present in the tissue of leaflet 3.The gram stains were negative for organisms.On leaflets 2 and 3 there was a thin layer of organizing fibrin with acute and chronic inflammation.According to the pathologist, healing or treated endocarditis was not "strongly favored" but could not be entirely ruled out as the cause.Correlation with clinical history would be required to confirm this.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 cause of the fold could not be conclusively determined.

(b)(6) 2019 mjr ¿ supplemental report needed to address analysis: d10, h3, h6.Explant was reported due to stenosis and structural valve deterioration.The investigation found that there was circumferential fibrous pannus ingrowth on both the inflow and outflow surfaces, which narrowed the inflow diameter.All three leaflets were fibrotically thickened.Leaflet 2 contained a fold which caused incomplete coaptation.Calcifications were present of leaflet 2 and 3.Degenerative changes were present in the tissue of leaflet 3.The gram stains were negative for organisms.On leaflets 2 and 3 there was a thin layer of organizing fibrin with acute and chronic inflammation.According to the pathologist, healing or treated endocarditis was not "strongly favored" but could not be entirely ruled out as the cause.Correlation with clinical history would be required to confirm.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 cause of the pannus formation, fold, calcifications and inflammation could not be conclusively determined.Calcification is a known event associated with tissue heart valves.
