The Effect of Ovation Stent-Graft System on Aortic Pulse Wave Velocity: Preliminary Report on 3 Cases

The inflow restriction caused by the stiff, inflatable O-rings does not necessarily coincide with significant increase of aortic stiffness in the early postoperative period. Furthermore studies with more hemodynamic indices and longer follow-up are needed to delineate the impact of the Ovation's unique structural pattern on central hemodynamics.
