title: Traumatic dehiscence of Medtronic Freestyle stentless bioprosthesis.
abstract: We report a case of deceleration injury causing traumatic dehiscence of a Medtronic Freestyle aortic bioprosthesis (Medtronic Inc, Minneapolis, MN) in a 70-year-old patient 5 years after a total root reconstruction. The patient presented with progressive exertional dyspnea 6 months after a significant impact during a hockey game. Intraoperatively, there was a posterior dehiscence of the proximal suture line and almost complete tear of the left coronary leaflet. At reoperation, the patient underwent reconstruction of the aortic root and Bentall procedure with a size 23 mechanical aortic valved conduit.
