Aortic Valve Replacement with the Labcor TLPB Supra™ Porcine Bioprosthesis: Intermediate Clinical and Echocardiographic Outcomes.

Background: The Labcor TBLP Supra™ prosthesis is a second-generation tissue valve that has evolved from the Labcor TBLP™ prosthesis, first introduced in 1984. The Supra prosthesis is a triple-composite porcine valve, with no specific anticalcification treatment being used in its production other than standard tissue fixation with 0.4% glutaraldehyde.
