Event Description
|
On (b)(6) 2015, a 21mm trifecta valve was implanted.On (b)(6) 2019, the valve was explanted due to regurgitation.Associated patient symptoms included dyspnea and heart failure.Upon explant, a hole was observed near one of the cusps.An unknown sized unknown device was successfully implanted.No patient consequences were reported.

Manufacturer Narrative

Explant was reported due to regurgitation.The investigation found that leaflets 2 and 3 contained a tear.All three leaflets had been previously dissected with excised tissue missing.All three leaflets were fibrotically thickened.There was fibrous pannus ingrowth on the outflow surface of leaflet 1.No inflammation or significant calcifications were present.The stent ring was distorted.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 tear could not be conclusively determined; however, the fibrous pannus ingrowth noted had the potential to induce increased stress on adjacent leaflets and create an unbalanced stress relief distribution between all leaflets during coaptation, leading to leaflet tears and reduced durability.
