Aortic Root Enlargement in Aortic Valve Replacement
Aortic Root Enlargement in Aortic Valve Replacement
Aortic valve disease is a progressive illness that varies from minor valve thickening lacking
 obstruction of blood stream to severe calcification and alteration of the valve leading to
 weakened leaflet motion. Aortic valve replacement is a usual operation but can be complicated
 by a small aortic annulus requiring the insertion of an aortic valve prosthesis.
 Prosthesis-patient discrepancy results in worse outcomes.
Prosthesis-patient discrepancy results in worse outcomes, including elevated left ventricular
 work, decreased left ventricular mass regression, and has also been linked with high
 mortality. Therefore, Aortic root posterior enlargement by autologous fixed pericardium to
 insert an Aortic valve prosthesis with size suitable to patient body surface area to avoid
 the previous worse outcome of patient prosthesis mismatch. In this study the investigators
 will try to identify the benefits of Aortic Root Enlargement in management of Small Aortic
 Annulus in Patients with severe valvular aortic stenosis
