In vivo testing of an intra-annular aortic valve annuloplasty ring in a chronic calf model.
OBJECTIVE To increase applicability and stability of aortic valve repair, a three-dimensional aortic annuloplasty ring has been developed for intra-annular placement. The goal of this study was to test the safety of this device with in vivo implantation in the calf model. METHODS In 10 chronic calves, the HAART annuloplasty ring was sutured to the aortic valve annulus using cardiopulmonary by...
متن کاملAn 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...
متن کاملCoronéo extra-aortic annuloplasty ring could stabilize even the pulmonary autograft annulus in a Ross operation.
The Ross procedure is an alternative technique to mechanical prosthesis and recent evidence suggests that it is associated with improved long-term survival and quality of life. However, late pulmonary autograft failure can occur more frequently in patients with significant dilation of the aortic annulus. Here, we present a technical modification of the Ross procedure--a case report of a patient...
متن کاملTranscatheter aortic valve implantation: early results of the FRANCE (FRench Aortic National CoreValve and Edwards) registry.
AIMS Transcatheter aortic valve implantation is a therapeutic alternative for high-surgical-risk patients with severe symptomatic aortic stenosis. Two models of prosthesis are currently commercialized in France, which can be implanted either via a transarterial or a transapical approach. The aim of the study was to evaluate in a national French registry the early safety and efficacy of transcat...
متن کاملAortic prosthetic ring annuloplasty: a useful adjunct to a standardized aortic valve-sparing procedure?
OBJECTIVE Dilation of aortic annulus, sinuses of Valsalva, and sinotubular junction (STJ) diameters are the characteristic lesions of aortic root aneurysm. The remodeling technique reduces STJ diameter and creates three neosinuses of Valsalva. Alternatively, the reimplantation technique reduces both annulus and STJ diameters to the detriment of aortic root dynamics. Although the remodeling tech...
