Successful 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...
متن کاملTricuspid valve repair: is ring annuloplasty superior?
OBJECTIVES Tricuspid regurgitation (TR) secondary to left heart disease is the most common aetiology of tricuspid valve (TV) insufficiency. Valve annuloplasty is the primary treatment for TV insufficiency. Several studies have shown the superiority of annuloplasty with a prosthetic ring over other repair techniques. We reviewed our experience with different surgical techniques for the treatment...
متن کاملAortic annuloplasty: a new aspect of aortic valve repair.
study because this is the technique that has been the most used in clinical practice for ventriculo-aortic junction reduction and stabilization. Of course, it has an effect on valve coaptation. It increased the coaptation by plications, or if you prefer, by closing the subcommissural triangle. This portion of the aortic root is just above what we considered to be the ventriculo-aortic junction,...
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 کاملValve repair using biodegradable ring annuloplasty: from bench to long-term clinical results
Annulus remodeling and stabilization with a ring is a necessary step in mitral and tricuspid valve repair to maintain effective leaflet coaptation and improve long-term results. Although conventional rings meet the basic needs of adults, they do not preserve the changes in shape and size occurring during the cardiac cycle, and do not allow growth of the native annulus in children. The bioring...
