The role of the Valsalva sinuses was widely studied in the past. Nevertheless, the ISO Standard 5840 prescribe the test to be performed on new prototypes does not require the presence of the sinuses. Aim of this work is to evaluate the influence of the compliance of aortic conduct with the anatomical shape of Valsalva sinuses on the performances of two polymeric heart valve called Poli-Valve. The results were compared with data obtained by using a rigid conduit as recommended by the Standard.

Abstract

The role of the Valsalva sinuses was widely studied in the past. Nevertheless, the ISO Standard 5840 prescribe the test to be performed on new prototypes does not require the presence of the sinuses. Aim of this work is to evaluate the influence of the compliance of aortic conduct with the anatomical shape of Valsalva sinuses on the performances of two polymeric heart valve called Poli-Valve. The results were compared with data obtained by using a rigid conduit as recommended by the Standard.
