Medtronic received information that during the implant of a transcatheter bioprosthetic valve, moderate-severe paravalvular leak was observed.Post implant, a balloon aortic valvuloplasty was performed with a 26 mm true balloon (non-medtronic).It was reported that the balloon was inserted between the two transcatheter bioprosthetic valves and crushed the inner valve.Severe central regurgitation was then noted and the procedure was converted to an open heart procedure.The transcatheter bioprosthetic valves were explanted and a new surgical aortic valve was successfully implanted.No other adverse patient effects were reported.(b)(4).This report reflects information received by fda in the form of a notification per 803.22 (b)(2).
