BACKGROUND: Surgical glues are used in mechanical, stentless bioprosthetic, and homograft aortic root replacements to seal and reinforce anastomotic suture lines. The aortic root normally undergoes substantial physiologic dilation and may be affected by the stiffness of applied sealants. We determined the material properties of four common commercial glues, comparing them with known properties of aortic root replacements. METHODS: Samples of BioGlue (CryoLife, Inc, Kennesaw, GA), CoSeal (Baxter Healthcare International, Palo Alto, CA), Tisseel (Baxter Healthcare Corp, Glendale, CA), and Crosseal (OMRIX Biopharmaceuticals, Inc, New York, NY) sealants underwent biaxial tensile testing...
