Surgical management of isolated congenital tricuspid regurgitation

Repair of Congenitally Absent Chordae in a Tricuspid Valve Leaflet with Hypoplastic Papillary Muscle Using Artificial Chordae

“…This is because it is difficult to predetermine the number of neochordae that will be necessary to achieve valve competence, and it is easy to rereconstruct new neochordae without injury to the hypoplastic papillary muscle when valve competence is not achieved after TV repair 5 . On the other hand, when the papillary muscle is hypoplastic, techniques where the proximal ends of the sutures pass through the free wall of the right ventricle, which is reinforced at both points with Teflon felt pledgets, are applicable for substitution of the papillary muscle 9,10 . Our patient, however, had a thinned right ventricle wall that affected RV loading; consequently, this method would have been unsuitable because of the potential for laceration of the right ventricle wall.…”

“…Chordal replacement using artificial chordae in the mitral position is an established technique, and its application with some modification to TV repair has been reported by some authors 9‐12 . Reddy et al described the use of artificial chords for chordal replacement and augmentation 9 .…”

Artificial chordae for pediatric mitral and tricuspid valve repair☆

“…A few cases have been reported, where artificial chords were inserted because of leaflet tethering due to short chordae or a total absence of chordae [10][11][12][13][14].…”

Repair of ruptured tendinous chords in the newborn with flail tricuspid valve and functional pulmonary atresia

“…It can be caused by various forms of congenital tricuspid valve disease [1,2], or by traumatic or nontraumatic rupture of the papillary muscle [3] or chordae. Urgent surgical treatment may be necessary in children, in some instances even in neonates [4].…”
