TCTAP A-093 The Prevalence of Leaflet Thrombosis in Intra-annular Versus Supra-annular Transcatheter Aortic Valve Prostheses

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...

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...

Aortic Valve Annular Sizing

An intra-annular 'hemispherical' annuloplasty frame for aortic valve repair.

BACKGROUND AND AIM OF THE STUDY A 'Hemispherical' model of aortic valve geometry was developed in which normal human cadaveric aortic valve leaflets could be represented as three hemispheres nested within a cylindrical aorta. By mathematically describing the junction between the leaflets and aorta, the normal three-dimensional annular geometry of the aortic valve could be defined. In this study...

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...
