This is being filed for a loss of column observed with the steerable guide catheter.It was reported that on (b)(6) 2022, the patient presented with degenerative mitral regurgitation (mr) grade 4, with a large left atrium, and a2 flail.Reportedly, the transseptal height was high, at 5.9 cm.Although the transseptal height was high and it was difficult to advance due to anatomy, the first mitraclip was successfully implanted.Another xtw mitraclip was attempted to be placed lateral to the first, however, the operator could not lose the excess height, created with the transseptal.Troubleshooting was performed; however, the xtw clip delivery system (cds) was unable to advance.It was determined that a new transseptal puncture was needed.The xtw cds and steerable guide catheter were removed without issue reported.During preparation of the same sgc, a loss of fluid column occurred.The sgc¿s fluid column would not hold.Another transseptal access was performed and a new sgc was used in replacement.The same xtw that had failed to advance earlier was re-advanced and was implanted lateral to the first mitraclip.After deployment, the clip opened while locked and a single leaflet device attachment (slda) had then occurred.The clip detached from the anterior leaflet, while remaining attached to the posterior.As treatment for the slda, a third xtw mitraclip (20224r366) was implanted without an issue reported, stabilizing the slda.The mr was reduced to grade 1-2.There was no adverse patient sequela.No additional information was provided regarding this issue.
