It was learned through implant patient registry and investigation, that a patient with a 23mm inspiris aortic valve was explant at implant due to obstruction of lad/circumflex artery.The device was replaced with a 21mm 11500a valve.Per medical records the patient initially underwent avr with a 23mm edwards inspiris valve for native as and ai.The valve was implanted and appeared to seat easily in the annulus but one of the struts of the valve was noted to be looped by the valve suture.The 23mm edwards valve was explanted ((b)(6) 2023) and replaced with a 23mm inspiris valve.The valve was inspected, and the lad/circumflex was obstructed by the strut adjacent to the left right commissure.It was elected to explant the 23mm inspiris valve replacing with a 21mm inspiris valve and graft the lad and circumflex arteries.Impella was placed due to poor lv function.Placement of impella was difficult due to the small size of the patients heart and it could not be positioned adequately leading to severe ai.It was elected to withdraw the impella device.Following removal of the impella, there was no transvalvular or perivalvular insufficiency.The patient oxygenation continued to deteriorate followed by lv failure.The patient was transferred to cvicu with a va ecmo and open chest.It was later learned that the patient expired on pod#2.This case involved a 69-year-old male with history of severe bicuspid av stenosis.

H10: additional manufacturer narrative: valve explant at implant is typically a result of inappropriate sizing, difficulty seating, distortion of the valve, valve displacement before/after frame expansion, and/or the patients anatomy, and not a malfunction of the device.The most likely cause is procedural factors, including the valve explanted was inadequate with regard to the patient's anatomy leading to an obstruction of the lad/circumflex artery.
