Event Description
|
Medtronic received information that during implant of this transcatheter bioprosthetic valve, the valve dislodged aortic upon release from the delivery catheter system (dcs) or while pulling the nose cone of the dcs through the valve.It was not able to decipher when the dislodge occurred.Subsequently a non-medtronic valve was implanted. it was reported that the patient had a tortuous anatomy with a 63 degree root angle and a possible type 1 bicuspid valve.The cusp overlap technique was unable to be used.

Conclusion: the device history record was reviewed and showed that this product met all manufacturing specifications for product released for distribution.No issues were identified that would have impacted this event.The reported event indicates that the valve dislodged aortic upon release from the delivery catheter system (dcs) or while pulling the nose cone of the dcs through the valve.Dislodgement of the valve by the distal tip is related to operator technique or experience; the evolut fx instructions for use, instructs ¿under fluoroscopic guidance, confirm that the catheter tip is coaxial with the inflow portion of the bioprosthesis¿ prior to drawing the dcs tip through the valve.In this case, it was reported that prior to withdrawing the delivery catheter system (dcs) the nosecone had been centered within the valve inflow.As reported, it was possible that the dcs could have been twisted or torqued as upon valve deployment one of the tabs would not release.The evolut system training material instructs the user to confirm paddle detachment prior to retrieving the system.The deployment knob should be turned slowly to allow the paddles to detach one at a time.If the paddle does not detach, the user is instructed to gently push on the system until the valve releases.In this, per the physician, the cause of the dislodgement was possibly the valve being higher than what it was thought to have been having to use the co-planar view.Additionally, ¿massive¿ tortuosity in the aorta and a 69-degree root angle possibly also contributed to the dislodgement.No images from the procedure were received for review; given the limited information, the root cause of the dislodgement event cannot be confirmed.Events of this type do not indicate a device malfunction or a failure to meet manufacturing specifications.Medtronic is submitting this report to comply with fda reporting regulations under 21 cfr parts 4 and 803.This report is based upon information obtained by medtronic, which the company may not have been able to fully investigate or verify prior to the date the report was required by the fda.Medtronic has made reasonable efforts to obtain more complete information and has provided as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.In particular, this report does not constitute an admission by anyone that the product described in this report has any ¿defects¿ or has ¿malfunctioned¿.These words are included in the fda 3500a form and are fixed items for selection created by the fda to categorize the type of event solely for the purpose of regulatory reporting.Medtronic objects to the use of these words and others like them because of the lack of definition and the connotations implied by these terms.This statement should be included with any information or report disclosed to the public under the freedom of information act.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.

Additional information was received which indicated a pre-balloon aortic valvuloplasty (bav) had been preformed.Prior to withdrawing the delivery catheter system (dcs), the nosecone had been centered within the valve inflow.As reported, it was possible that the dcs could have been twisted or torqued as upon valve deployment one of the tabs would not release.Per the physician, the cause of the dislodgement was possibly the valve being higher than what it was thought to have been having to use the co-planar view.Additionally, ¿massive¿ tortuosity in the aorta and a 69 degree root angle possibly also contributed to the dislodgement.No additional adverse patient effects were reported.Updated data: h6 additional device code corrected data: h6 method and annex g code.Medtronic is submitting this report to comply with fda reporting regulations under 21 cfr parts 4 and 803.This report is based upon information obtained by medtronic, which the company may not have been able to fully investigate or verify prior to the date the report was required by the fda.Medtronic has made reasonable efforts to obtain more complete information and has provided as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.In particular, this report does not constitute an admission by anyone that the product described in this report has any ¿defects¿ or has ¿malfunctioned¿.These words are included in the fda 3500a form and are fixed items for selection created by the fda to categorize the type of event solely for the purpose of regulatory reporting.Medtronic objects to the use of these words and others like them because of the lack of definition and the connotations implied by these terms.This statement should be included with any information or report disclosed to the public under the freedom of information act.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.

Additional information was reported which indicated that as a result of the co-planar view, the cusp overlap technique could not be achieved.The approximate implant depth was 1 to 2 mm on the non-coronary cusp (ncc) and 1 to 2 mm on the left coronary cusp (lcc).Updated b5.Medtronic is submitting this report to comply with fda reporting regulations under 21 cfr parts 4 and 803.This report is based upon information obtained by medtronic, which the company may not have been able to fully investigate or verify prior to the date the report was required by the fda.Medtronic has made reasonable efforts to obtain more complete information and has provided as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.In particular, this report does not constitute an admission by anyone that the product described in this report has any ¿defects¿ or has ¿malfunctioned¿.These words are included in the fda 3500a form and are fixed items for selection created by the fda to categorize the type of event solely for the purpose of regulatory reporting.Medtronic objects to the use of these words and others like them because of the lack of definition and the connotations implied by these terms.This statement should be included with any information or report disclosed to the public under the freedom of information act.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.
