One-year hemodynamic comparison of Perimount Magna with St Jude Epic aortic bioprostheses

Abstract

Introduction: Cardiac surgeons are using more bioprosthetic valves due to theageing population as well as to improvements that have been made to these implants. We sought to compare the 1-year hemodynamics of two commercially available valves by echocardiographic parameters. Material and methods: Retrospective review of our institutional database revealed 69 patients who received either Perimount Magna (n = 33) or St Jude Epic (n = 36) valves in the aortic position with no other valve surgery between June 2004 and March 2006. All patients received transthoracic echocardiography at 1 year. Comparisons between groups were made at baseline and at 1-year follow-up. In addition, a pairwise compar..
