Real Structural Valve Deterioration of the Mitroflow Aortic Prosthesis: Competing Risk Analysis.

Introduction And Objectives: The Mitroflow aortic prosthesis is a bovine pericardial bioprosthesis specially designed to increase the valve area in relation to its size. There is controversy regarding the pattern of structural valve deterioration (SVD). Our aim was to determine the cumulative incidence of SVD, risk factors influencing its occurrence, and its impact on mortality.
