Preferred method for insertion of the Toronto Stentless Porcine Valve.

The Toronto Stentless Porcine Valve has been extensively used for aortic valve replacement. A standardized, detailed description of a preferred operative technique has been absent from the literature. A method is described that stresses (a) proper position and orientation of the aortotomy, (b) debridement of the diseased native valve, (C) proper sizing of the aortic root and choice of prosthesis and (d) implantation of the valve. Using this technique, the prosthesis can be reproducibly implanted with relative ease, without valvular insufficiency or coronary obstruction.
