Product analysis: upon receipt at medtronic's quality laboratory, visual examination revealed the band was discolored and stained showing evidence of blood contact.Small needle holes were observed along the ring showing placement of implantation sutures.The ring appears to have been cut on both ends.Radiography showed no evidence of fractures on the ring.Conclusions: analysis showed no issues were observed with the annuloplasty ring related to the event.Surgeons often attempt to rep air valves in lieu of replacing them in an effort to preserve the native mitral anatomy.There are times when valve repair is attempted using a repair device and subsequent post-repair evaluation demonstrates an inadequate result.This is potentially due to, but not limited to, suboptimal anatomy, surgical technique, or inappropriate sizing, rather than a malfunction of the device.In this case, it was reported that the ring was incorrectly sized, and a smaller ring was implanted.If information is provided in the future, a supplemental report will be issued.
