Thrombocytopenia after Implantation of the Perceval, Intuity, and Sapien Aortic Valve Prostheses.

 We found a significant platelet count reduction in all three bioprostheses which was more marked in the Perceval group. The platelet count reduction was transient and fully recovered in the Intuity and Sapien groups, whereas the Perceval group showed only a partial platelet count recovery. However, bleeding complications were not different between the three bioprostheses.
