Manufacturer Narrative

Medtronic received additional information that approximately 3 months post conduit implant, cardiac catherization revealed severe pulmonary stenosis at the distal portion of the conduit.Five months post implant the conduit was replaced due to stenosis with elevated gradients, and patch aterioplasty was performed on the patient's pulmonary artery branches.During the explant procedure, dense fibrous tissue and calcification were noted in the distal portion of the conduit.It was reported thatthis portion of the conduit also appeared to have shrunk in size.During the procedure, bleeding was noted and was determined to be originating from a collateral branch of the pulmonary artery.The bleeding was controlled with ligation and titanium clips, and the patient tolerated the procedure well.No additional adverse patient effects were reported.  a4: patient weight added h6: coding updated 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.
