Hydrodynamic ex vivo analysis of valve-sparing techniques: assessment and comparison.

ABSTRACT:

Objectives

Valve-sparing procedures are surgical techniques allowing to restore adequate function of the native aortic valve by replacing the dysfunctional ascending aorta with a prosthetic conduit. A number of techniques are currently used, such as Yacoub's remodelling and David's reimplantation, based on a regular straight conduit. More recently, the De Paulis proposed the use of bulging conduits to reconstruct the shape of the Valsalva sinuses. This work investigates the impact of the valve-sparing technique on the aortic valve function.

Methods

The performance of 3 porcine aortic roots (Medtronic Freestyle™) was assessed in a cardiovascular pulse duplicator before and after performing 3 alternative valve-sparing procedures: David's reimplantation, Yacoub's remodelling an
