Hemodynamic performance of mitroflow aortic pericardial bioprosthesis - optimizing management for the small aortic annulus.

Background: Documentation of the hemodynamics of the Mitroflow aortic pericardial bioprosthesis has been incomplete. The aim of the study was to provide reference effective orifice areas for the implant calculation of effective orifice area indexes to avoid prosthesis-patient mismatch.

Methods: Echocardiograms were evaluated in 55 patients (39 females, 16 males), mean age 77.
