OBJECTIVES: To retrospectively review our experience with artificial chords in mitral and tricuspid reconstructive surgery in children. METHODS: All consecutive paediatric ( <18 years) patients who underwent mitral or tricuspid valve reconstruction with the use of artificial chords in our centre in the past 15 years were retrospectively analysed. RESULTS: Thirty-nine patients (age 3 days to 17 years) underwent reconstruction of the mitral (n = 27) or tricuspid (n = 12) valve using artificial chords. Mean number of chords was 3.5 +/- 1.7. In 26 of 27 mitral valve patients, chords were placed on the anterior leaflet, in one on the posterior leaflet. In 10 of the 12 tricupid valve, patients chords were placed on the anterior leaflet and in 2 on the septal leaflet. All mitral patients underwent annuloplasty (10 bilateral Wooler-Kay and 17 rigid ring annuloplasty). Ten of the 12 tricuspid patients underwent annuloplasty (1 rigid ring and 9 commissural plication). Follow-up was after 8.7 +/- 5.5 years. There was no early or late mortality. The actuarial freedom from reoperation rates at 1, 5 and 10 years were 95%, 91% and 81%, respectively. No reoperations occurred in the tricuspid group. In the mitral group, there were 2 early failures and 3 late reoperations due to mitral stenosis. Restricted leaflet motion probably caused by the artificial chords was seen in only 1 patient. CONCLUSIONS: Our data show that long-term durability of mitral and tricuspid valve reconstruction using artificial chords in children is good. Despite patient growth, restricted leaflet motion by the artificial chords does not seem to form a major problem
