Early postoperative hemodynamic performances of stented versus stentless aortic xenografts in aortic valve replacement in elderly patients: a comparative study

Abstract

BACKGROUND AND AIM: Surgical valve replacement is the most commonly performed for aortic stenosis. Randomized trials comparing stentless to stented bioprostheses for aortic valve replacement in elderly are scarce. The aim of our study was comparing and evaluating the early hemodynamic performances of Hancock (TM) stented and FreeStyle (TM) stentless xenograft aortic valves in aortic valve replacement in elderly patients.
