Ex vivo evaluation of the Ozaki procedure in comparison with the native aortic valve and prosthetic valves.

ABSTRACT:

Objectives

We investigated the hydrodynamic performance and cusp kinematics of the Ozaki neocuspidized aortic valve in comparison with the native aortic and prosthetic valves in an ex vivo study.

Methods

Native aortic valves of swine hearts were replaced by aortic valve substitutes, and their hydrodynamic performance (effective orifice area and mean pressure gradient) was evaluated in a mock circulation under defined conditions. The following aortic valve substitutes were investigated: native aortic valve, Ozaki valve, Perimount Magna Ease, Trifecta and St. Jude Medical Masters. All prosthetic valves had a labelled size of 21 mm.

Results

The Ozaki valve and native aortic valve showed a similar and significantly larger orifice area than all investigated prosthetic valv
