Randomized Sizing and Hemodynamic Study Mitroflow vs. Magna

January 6, 2012 updated by: Sorin Group USA, Inc.

A Randomized Study to Compare Sizing, Implant Techniques and Hemodynamic Performance Between the Mitroflow and the Carpentier-Edwards Magna Pericardial Tissue Valves in the Aortic Position

The purpose of this study is to compare sizing,implant techniques, and hemodynamics between the Mitroflow Pericardial Aortic Valve and the Edwards Magna Heart Valve.

Study Overview

Detailed Description

Comparisons of valve types are often made according to labeled valve sizes. There is growing evidence that in the majority of cases the actual sizer and valve dimensions vary from the labeled diameters, which may not be related to any hemodynamically meaningful dimension. The disagreement between the true valve dimensions and the labeled valve size may render comparisons based on labeled size meaningless
