Implantation of the Toronto SPV Stentless Porcine Bioprosthesis in Dilated Ascending Aorta

In the presence of severe dilatation of the ascending aorta the implantation of a Toronto SPV stentless bioprosthesis is compromised by the risk of postoperative central regurgitation. A modification of the implantation technique is described that restores the normal shape of the ascending aorta and...

Summary:In the presence of severe dilatation of the ascending aorta the implantation of a Toronto SPV stentless bioprosthesis is compromised by the risk of postoperative central regurgitation. A modification of the implantation technique is described that restores the normal shape of the ascending aorta and thereby avoids the risk of dysfunction of the prosthesis.
