Event Description

Medtronic received information from a literature article regarding a comparison of the short- and long-term outcomes for patients who underwent aortic valve-sparing reimplantation (david procedure) or aortic root replacement (bentall procedure) operations.All data were retrospectively collected from a single center between january 2000 and december 2015.The study population included 523 patients (261 david procedures, 262 bentall procedures) and was predominantly male with a mean age of 53 years.Of the 262 patients who underwent a bentall procedure, 150 were implanted with medtronic devices: freestyle (55), mosaic (1), ats open pivot standard (6), and ats aortic valved graft (88).No serial numbers were provided.The overall mortality for patients requiring reoperation for valve-related events was 15.4% (4 patients).No further details were provided.Among all patients in the bentall group, the in-hospital and 30-day mortality included 4 and 5 patients, respectively.The study used non-medtronic devices in addition to the freestyle, mosaic, ats open pivot standard, and ats aortic valved graft.The type of device implanted in each patient who died was not reported.Based on the available information, medtronic product was not directly associated with any of the deaths.Among all patients in the bentall group, adverse events included: bleeding requiring hospitalization and/or reoperation; redo surgery due to endocarditis, unspecified aortic insufficiency, or aortic stenosis; new permanent pacemaker implantation; cerebrovascular accident; myocardial infarction; low cardiac output; sepsis; deep sternal wound infection; endocarditis without redo surgery; and reduced left ventricular ejection fraction.Based on the available information, medtronic product may have been associated with the adverse events.No additional adverse patient effects or product performance issues were reported.
