[Aortic valve replacement with stentless bioprosthesis: operative methods and pitfalls].
Operative methods and pitfalls of aortic valve replacement using either Toronto SPV and Freestyle prosthesis were described. Precise transverse aortotomy, straight inflow-suture line, and outflow suture not obstructing coronary orifices are the points for the standard procedure. For bicuspid aortic valves, care should be taken for the anomaly of coronary orifices. Our experience with 24 consecutive cases indicated that oversizing of the prosthesis was possible in stentless bioprosthesis.
