CRT-600.01 Comparison of Valve Performance of the Intra-Annular Self-Expanding Portico™ Transcatheter Aortic Valve With Contemporary Supra-Annular Self-Expanding and Intra-Annular Balloon-Expandable Valves: Insights From the PORTICO IDE Trial

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...

Options for transcatheter aortic valve implantation: comparing self-expanding with balloon- expandable valves

Options for transcatheter aortic valve implantation: comparing self-expanding with balloonexpandable valves The advent of transcatheter aortic valve implantation (TAVI) has offered clinicians the option of managing patients with severe symptomatic aortic stenosis, who are at high operative risk, the possibility of replacing the aortic valve without requiring a full open-heart surgery. Two techn...

A new self-expanding aortic stent valve with annular fixation: in vitro haemodynamic assessment.

OBJECTIVE Balloon-expandable stent valves require flow reduction during implantation (rapid pacing). The present study was designed to compare a self-expanding stent valve with annular fixation versus a balloon-expandable stent valve. METHODS Implantation of a new self-expanding stent valve with annular fixation (Symetis, Lausanne, Switzerland) was assessed versus balloon-expandable stent val...

First reported case of transcatheter mitral valve implantation in mitral annular calcification with a fully repositionable and self-expanding valve.

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...
