Patient Problem No Known Impact Or Consequence To Patient (2692)

Event Date 11/11/2019

Event Type  Injury  

Event Description

On (b)(6) 2019, a perceval size l (pvs25) implant attempt occurred.The device was correctly collapsed using the correct procedure and with good collapsing pressure.It was noted that the cap on the end of the holder only just captured the entire circumference of the inlet ring (tissue end).The valve was deployed but the surgeon noted that it was higher on one side as he could see annulus.The device was consequently explanted (leaving the guiding sutures in place) and a decision was made to recollapse the same device.Two other attempts to collapse the device were made with the same accessories but on each attempt, the inlet ring was not fully enclosed by the holder cap - part of it was protruding.Another attempt of collapsing was made with a new holder, but the same outcome was observed.A new valve pvs25 was opened and used with the second accessory kit.The valve was correctly collapsed and deployed with no issues.

Event Description

On (b)(6) 2019, a perceval size l (pvs25) implant attempt occurred.The device was correctly collapsed using the correct procedure and with good collapsing pressure.It was noted that the cap on the end of the holder only just captured the entire circumference of the inlet ring (tissue end).The valve was deployed as expected but was not positioned correctly.It was noticed that the valve sat slightly higher on one side, likely due to inadequate tension on the guide sutures.The device was consequently explanted, leaving the guiding sutures in place, and a decision was made to recollapse the same device.Two other attempts to collapse the device were made with the same accessories but on each attempt, the inlet ring was not fully enclosed by the holder cap - part of it was protruding.Another attempt of collapsing was made with a new holder, but the same outcome was observed.A new valve pvs25 was consequently opened and used with the second accessory kit.The latter valve was correctly collapsed and deployed with no issues.A short increase in the cross-clamp time is reported for this event (less than 20 min).The patient remained stable throughout the procedure, with an uneventful recovery and discharge.

Manufacturer Narrative

The device was returned to the manufacturer and it was received on 28 feb 2020.Along with the prosthesis, two accessory kits were also received, although it was not specified with which order the accessories were used.After decontamination, the valve was visually inspected according to the standard procedure without highlighting elements of non-conformity.A collapsing simulation was then performed using the returned prosthesis and both accessory kits.The valve was correctly collapsed and released with both accessories received.Based on the performed analysis, the reported event cannot be explained by any factor intrinsic in the involved prosthesis or accessories because it was not possible to reproduce the claimed collapsing difficulties.As reported, the valve was correctly collapsed at the first attempt of implant, which failed due to malpositioning attributed to the procedure (i.E.The tension applied on the guiding sutures).Based on livanova's experience, it is possible that the claimed collapsing difficulties could be related to an incomplete radial reduction of the valve or to a valve mispositioning (i.E.Too far forward in the dual collapser), which makes it difficult to correctly capture of the inflow side of the valve.Nevertheless, it should be noted that an explanted prosthesis must not be reimplanted per the perceval ifu, as integrity is no longer ensured.As such, the decision to attempt to re-implant the same prosthesis was made off label.
