(b)(4).The explanted device was returned to edwards for analysis.As received, the ring exhibited minimal host tissue overgrowth.Suture threads were evident in the sewing ring.No visible damage to band was observed in the x-ray.Based on the product evaluation, we are unable to confirm the clinical observation.Ring or valve dehiscence may occur early or late.When it occurs in the early post-operative period, it is typically a result of an inadequate valve repair or prosthetic valve implantation in combination with friable myocardial tissue.In this case, the health care provider claimed that the dehiscence was not due to a device malfunction nor quality deficiency.No further actions are possible with the available information.
