Abstract[English]
Mitral valve regurgitation can be ameliorated by creating one passageway between the right atrium and the left ventricle at a portion of the tricuspid annulus that is directly above the interventricular septum and creating another passageway through an outer wall of the left ventricle near at least one of the left-ventricular papillary muscles. A support bar is positioned within the right atrium in contact with a septal portion of the tricuspid annulus, and a support plate is positioned against the outer wall of the left ventricle adjacent to the second passageway. The support plate is pulled towards the support bar using a tether under tension that runs between the first support plate and the support bar and passes through both passageways. And the tension in the tether moves the roots of the chordae closer to the mitral valve, which ameliorates the mitral valve regurgitation.[French]
Selon l'invention, la régurgitation de la valve mitrale peut être améliorée en créant un passage entre l'atrium droit et le ventricule gauche dans une partie de l'anneau tricuspide qui se trouve directement au-dessus du septum interventriculaire et en créant un autre passage à travers la paroi externe du ventricule gauche près d'au moins un des muscles papillaires du ventricule gauche. Une barre de support est positionnée dans l'atrium droit en contact avec une partie septale de l'anneau tricuspide, et une plaque de support est positionnée contre la paroi externe du ventricule gauche adjacente au second passage. La plaque de support est tirée vers la barre de support à l'aide d'un lien sous tension qui passe entre la première plaque de support et la barre de support et traverse les deux passages. La tension de l'attache rapproche les racines du cordage tendineux de la valve mitrale, ce qui améliore la régurgitation mitrale.
