Case ReportsTransient dysfunction of the freestyle stentless xenograft
Section snippets
Comment
Because it has no stent or sewing ring, the Freestyle bioprosthesis exhibits an enlarged orifice area and a reduced transvalvular pressure gradient. Early postoperative regression of left ventricular hypertrophy has been reported using this device. Because it is supplied as a complete aortic root, it is possible to modify the implantation technique to deal with a variety of native root conditions [2].
Sintek and colleagues [3] have reported an early postoperative reduction in valve pressure
