Medtronic received information via literature regarding clinical outcomes of valve-sparing root replacement (vsrr) compared with those of conventional root replacement with the use of a bioprosthetic valve-conduits for aortic root aneurysms.This study compared the operative and midterm results.All data was collected from a single center between the years of 2002 to 2015.The study included 707 patients, predominantly male with a mean age of 53 years old.A total of 425 patient were implanted with a bioprosthetic valve-conduit of multiple manufacturers.A total of 111 of the 425 patients were implanted with a medtronic freestyle or mosaic device, serial numbers were not provided.Among all patients adverse events included: bleeding, prolonged ventilator, intra-aortic balloon pump placement, renal failure, transient ischemic attack (tia), stroke, permanent pacemaker implant, and deep sternal infection.Based on the available information, these events may have been attributed to a medtronic product.
