(Study replaced by an observational study)
The primary objective of this study is to compare two different regimens of therapy, AVK and ASA (aspirin), in the early postoperative period after aortic valve replacement with SJM Epic™ or SJM Epic™ Supra Porcine Bioprosthetic Heart Valve by establishing the adverse event free survival rate at 3 month post intervention follow-up of the 2 groups(with special focus on thromboembolic events and bleedings).
