  • Title: Successful dilatation of the small aortic root for implantation of a larger valve prosthesis.
    Author: Bartels C, Sievers HH.
    Journal: J Heart Valve Dis; 1999 Sep; 8(5):507-8. PubMed ID: 10517391.
    Abstract:
    Optimal hemodynamic performance is of paramount importance when implanting a prosthesis in a patient with a small aortic annulus. In order to avoid prosthesis size/patient body surface area mismatch, current techniques advocate aortic annulus patch enlargement or the use of a supra-annular prosthesis to ensure the implantation of an appropriately sized aortic valve. We present the first description of mechanical dilatation of a small aortic annulus as a simple alternative method.
