A smart method of intraoperative explantation of an aortic bioprosthesis.

Structural prosthetic valve deterioration and nonstructural dysfunction are two common causes of nonfatal valve events following implantation of a bioprosthetic valve. Using caution and skill, implantation of a bioprosthesis is relatively easy. On the other hand, explantation of a bioprosthesis is a challenging and time-consuming procedure. We have developed a surgical technique by which we were able to ameliorate this troublesome situation in a 79-year-old man with aortic stenosis in whom we had to intraoperatively explant the bioprosthesis that we have put in initially. Another bioprosthesis of the same kind was used to replace the old prosthesis with the rest of his postoperative course until dismissal being eventless.
