Leaflet Replacement for Aortic Stenosis Using the 3f Stentless Aortic Bioprosthesis: Midterm Results

Its unique design makes the 3f aortic bioprosthesis less complex to implant than conventional stentless valves, as only a single suture line is necessary. The hemodynamic profile and clinical performance of the prosthesis are inconsistent with the established stentless valves, especially with regard to higher incidence of neurologic complications seen during the follow-up.
