    Abstract:
    BACKGROUND: Our study is aimed at evaluating the mid-term surgical outcomes of mitral valve repair in children using various chordal reconstructive procedures (autologous in situ chords or artificial chords). METHODS: A retrospective analysis of 154 patients who underwent mitral valve repair using various chordal reconstructive procedures from 1992 to 2012. Patients were divided into group A and group B based on use of artificial chords and autologous in situ chords, respectively, for the repair. There were 102 (66.2%) patients in group A and 52 (33.8%) patients in group B. The mean age at repair was 11.1 ± 4.5 years. Associated cardiac anomalies were found in 94 (61%) patients. RESULTS: The median follow-up period was 4.2 years (Interquartile range: 2.0-9.9). There were two (1.3%) early deaths and five (3.2%) late deaths. There was no significant difference in survival at 15 years between the two groups (group A: 91.8% vs group B: 95.1%; P = .66). There was no significant difference in the freedom from reoperation at 15 years between group A (79.4%) and group B (97.2%; P = .06). However, there was significant difference in freedom from valve failure between group A (56.5%) and group B (74.1%; P = .03). Carpentier functional class III and postoperative residual mitral regurgitation (2+ MR, ie, mild-moderate MR) were the risk factors for valve failure. CONCLUSIONS: Severity of the disease and its progression has profound effect on the valve repair than the technique itself. Both chordal reconstructive procedures can be used to produce satisfactory results in children.
