Manufacturer Narrative

Calcification is a well-recognized failure mode of bioprosthetic valves.Many factors contribute to the onset and propagation of calcification.These include patient factors (age, disease state, pharmacological intervention, etc.), and mechanical stress related to the valve's hemodynamic performance.Though numerous studies have been conducted on preventive calcification strategies in bioprosthetic heart valves, the causes of calcification are not fully understood and there are still no mechanisms or medical therapies which fully prevent bioprostheses from calcifying.Although patient factors are believed to play a crucial role in the development in bioprosthetic tissue calcification, the underline mechanism is still not fully understood.The device was not returned for evaluation, as it remains implanted.The root cause of this event cannot be conclusively determined.However, it is likely that patient related factors and the progression of the underlying valvular disease pathology contributed to the event.The device history record (dhr) was reviewed and showed that this device met all manufacturing and sterilization specifications for product release prior to distribution.No issues were identified that would have impacted this event.Edwards will continue to review and monitor all events.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.

Event Description

It was reported via clinical safety that a patient with a 23mm aortic valve is being evaluated for a valve-in-valve procedure due to severe stenosis, regurgitation, mildly thickened and calcified leaflets, mildly reduced range of motion, and mild pvl after an implant duration of 6 years and 10 months.The patient presented with sob and nyha class ii.
