Event Description

Medtronic received information that 13 years and 9 months post implant of this 12mm pulmonary valved conduit in a (b)(6) old pediatric patient, it was replaced valve-in-valve with a transcatheter bioprosthetic pulmonary valve deployed to 22mm.The reason for replacement was not reported.No additional adverse patient effects were reported.

Manufacturer Narrative

Medtronic received additional information that following the implant of this conduit in a 4 month old pediatric patient, progressive stenosis of the conduit developed.It was reported that this was due to both intimal growth and interval somatic growth.As a result, the patient was taken to the catheterization laboratory 4 months and 20 days post conduit implant.During the procedure, severe acute obstruction developed and a balloon angioplasty was attempted.It was reported that this resulted in an intimal tear and thrombosis.As a result, the patient was taken to the operating room.Upon explanting the conduit, the intimal dissection of the conduit was confirmed, as well as neo-intimate "buildup" within the conduit.A pulmonary homograft was subsequently implanted.No additional adverse patient effects were reported.A2: age corrected.A4: weight added.B3: event date corrected.G4: date mfg received corrected.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.
