“…23 Similarly, several different malformations may lead to varying degrees of mitral insufficiency, such as the prolapse of the anterior leaflet due to elongation and rupture or absence of the chordae tendineae. 24 We believe that our results can be applied to fetuses with valve insufficiency or stenosis, so as to obtain a new monitoring parameter for intrauterine heart function.…”

“…The use of the ePTFE sutures for artificial chordae in the mitral position in adult patients has been an established technique for more than three decades with satisfactory results. 12,15 -17 Although the published literature has shown encouraging midterm and long-term results of these artificial chordae for mitral valve repair in children, 18,19 its application to the tricuspid valve was first reported by Bortolotti et al in 1993 and subsequently by Zussa in 1996. 20,21 The unique advantages of ePTFE as artificial chordae are well established and include ready availability, low cost, ease of use, and encouraging midterm durability in children.…”

Background: Papillary muscle rupture in the perinatal period is a rare event that leads to severe mitral or tricuspid insufficiency due to a flail leaflet. Neonatal tricuspid chordal reconstruction for this condition is rarely reported. Early recognition and treatment have the potential to be lifesaving. We present our surgical experience with five such patients, along with their midterm follow-up. Methods: Between August 2010 and November 2012, five neonates (aged 1-30 days) underwent surgery for severe atrioventricular valve regurgitation. All neonates had severe tricuspid regurgitation due to ruptured chordae. In addition, two had moderate mitral regurgitation; one due to ruptured chordae of the posterior mitral leaflet and the other due to prolapse of the anterior mitral leaflet. All underwent emergent surgery where the ruptured chordae to the anterior tricuspid leaflet were replaced with neochordae made with expanded polytetrafluoroethylene (ePTFE) suture. The mitral valve was repaired in two patients. Results: All patients survived surgery without the need for postoperative mechanical circulatory assist. Predischarge echocardiograms showed good coaptation of tricuspid and mitral leaflets with minimal regurgitation in all. At follow-up between 75 months to 102 months, four patients had excellent outcomes with less than mild tricuspid regurgitation. One child with flail tricuspid and mitral leaflets developed progressive tricuspid and mitral regurgitation requiring surgical re-repair at 20 months following the initial surgery. Conclusion: Repair of chordal rupture of the tricuspid valve in neonates using e PTFE neo-chordae can provide acute salvage and gratifying midterm results in the management of this potentially fatal condition.

“…However, promising results have been achieved with the use of the artificial chordae of the mitral valve. Freedom from reoperation with chordal placement in the mitral valve position was 94.7% at 5 years and 89.5% at 8 years [8]. Considering that PTFE sutures lack the possibility of growth, further studies on the TV position in neonates is warranted.…”

Severe tricuspid regurgitation resulting from a flail leaflet is a rare cause of neonatal cyanosis. We report a neonate with profound cyanosis and severe tricuspid regurgitation caused by a rupture of the papillary muscle supporting the anterior leaflet, without other structural heart defects. Ductal patency could not be established. The repair of the tricuspid valve was performed after initial stabilization by using extracorporeal membrane oxygenation.

Midterm results of mitral valve repair with artificial chordae in children

Abstract: Mitral valve repair with expanded polytetrafluoroethylene sutures in children demonstrated favorable midterm outcome. The procedure is safe and effective, with potential for patients' growth.
