Event Description

Medtronic received information via literature regarding the longevity of valved conduits used in right ventricular outflow tract reconstruction.All data were collected between 1997 and 2013.The study population included 119 patients (mean age 9 years; mean weight 29 kg), 50 of which were implanted with a medtronic contegra valved conduit and 36 were implanted with a medtronic hancock valved conduit.No serial numbers were provided.The surgical mortality rate was 1.7% and late mortality rate 2.6% (reported to be not related to conduit failure).Multiple manufacturers were noted in the literature; based on the limited available information, medtronic product did not cause or contribute to these deaths.Among all patients, adverse events included: reoperation and/or intervention (defined as conduit dilatation or valve replacement).Multiple manufacturers were noted in the literature; however, based on the available information, medtronic product may have caused or contributed to these adverse events.No additional adverse patient effects or product performance issues were reported.
