The manufacturing and material records for the perceval plus heart valve, model #pvf-m, s/n # (b)(4), as they pertain to the reported event, were retrieved and reviewed by the manufacturer¿s quality engineering.The results confirmed that this valve satisfied all material, visual, and performance standards required for a (model #pvf-m) perceval plus heart valve at the time of manufacture and release.Since the device was not returned to the manufacturer at the time of the event, and no further information was received on its disposition, no further investigation is possible at this time.The manufacturer attempted to retrieve additional information on this event, and the device involved.However, no further information has been provided to date, despite the manufacturer's attempts.Based on the available information, it is not possible to establish a definitive root cause for the reported event.However, from the document review performed, no manufacturing deficiencies were identified.Given that the perceval plus valve pvf-m was replaced with a smaller perceval valve pvs21, the most probable root cause based on the available information can be traced to a device mis-sizing (use error).Should any further information be received in the future, the manufacturer will provide an update to this reporting activity.Unknown disposition.
