Is the Mid-term Hemodynamic Performance Different Between the BioValsalva and BioIntegral Aortic Valved Conduits after Aortic Root Replacement?

Methods: Between July 2008 and June 2014, a total of 55 patients underwent aortic root replacement using BioValsalva (BV) conduit (n=27) or BioIntegral (BI) conduit (n=28) in the University Hospital of Essen. The indication for surgery was aneurysm of aortic root in 41 patients (76.4%), acute type A aortic dissection in 11 patients (20%), aortic valve endocarditis with abscess in 2 patients (3.6%). To evaluate the hemodynamic performance of the prosthetic valve, the mean pressure gradient (MPG) and the effective orifice area (EOA) were measured. Follow up was performed within 5 years.
