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...
متن کاملExternal subcommissural annuloplasty to prevent regurgitation in the pulmonary autograft.
In pediatric patients, the further growth potential is a major advantage in using the pulmonary autograft (Ross procedure). The authors describe a modified annuloplasty technique that appears to prevent the development of undesirable aortic regurgitation associated with root enlargement while not affecting overall tissue growth in the autograft.
متن کاملIn 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 کاملRepair of functional tricuspid regurgitation: comparison between suture annuloplasty and rings annuloplasty.
BACKGROUND The purpose of this study was to review our experience with modified De Vega tricuspid annuloplasty versus ring annuloplasty for treating functional tricuspid regurgitation (TR). METHODS In all, 448 consecutive patients undergoing tricuspid annuloplasty with concomitant procedures between 2000 and 2012 were included. Modified De Vega annuloplasty was performed in 216 patients (grou...
متن کاملSuccessful bicuspid aortic valve repair using external aortic annuloplasty.
A 33-year-old man presented with severe aortic insufficiency due to a prolapsed bicuspid aortic valve. The ventriculoaortic junction was dilated to 29 mm without root dilatation, and external ring annuloplasty was performed using a Gelweave (Terumo, Tokyo, Japan) graft to reduce the size to 22 mm. The leaflets were repaired by dividing and suturing a raphe between the right and left cusps. This...
