Intra-Supra Annular Aortic Valve and Complete Supra Annular Aortic Valve: A Literature Review and Hemodynamic Comparison

Matched Comparison of Two Different Biological Prostheses for Complete Supra-annular Aortic Valve Replacement.

Objective The aim of this retrospective study was to evaluate the hemodynamic performance of the St. Jude Medical Trifecta (SJM Trifecta; St. Jude Medical, St Paul, Minnesota, United States) and the Carpentier-Edwards Perimount Magna Ease (CEPM Ease; Edwards Lifesciences, Irvine, California, United States) bioprostheses early postoperative and at 1 year. Methods From October 2007 to October 200...

Hemodynamic comparison of bioprostheses for complete supra-annular position in patients with small aortic annulus.

OBJECTIVES The present study evaluates complete supra-annular bioprostheses in patients with an aortic annulus of 18 to 23 mm in diameter. BACKGROUND Aortic valve replacement in patients with small aortic annulus using stented bioprostheses is often associated with unsatisfactory hemodynamic results and high incidence of patient-prosthesis mismatch. METHODS Between February 2000 and January...

Aortic Valve Annular Sizing

First dutch experience of the accurate neo self-expanding supra-annular valve for valve-in-valve transcatheter aortic valve implantation

We describe the first two cases of valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) using Accurate Neo device in the Netherlands. A 73-year-old man underwent transfemoral ViV-TAVI for severe stenosis in his 25-mm Carpentier-Edwards Perimount bioprosthesis. After balloon predilatation, a mediumsize Accurate Neo was advanced to the bioprosthetic annulus. First, its upper part w...

Aortic Annular Enlargement during Aortic Valve Replacement

In the surgery of aortic valve replacement is always attempted, as much as possible, to implant the larger prosthesis with the mains goals to enhance the potential benefits, to minimise transvalvular gradient, decrease left ventricular size and avoid the phenomenon of patient-prosthesis mismatch. Implantation of an ideal prosthesis often it is not possible, due to a small aortic annulus. A vari...
