Pediatric patients with moderate or severe mitral valve regurgitation who had undergone mitral valvuloplasty between September 2016 and August 2023 were included. Kaplan-Meier survival analysis was used to assess freedom from both mitral valve deterioration and cardiovascular death. Univariate and multivariate Cox regression analyses were performed to identify potential risk factors.</p><p><strong>Results: </strong>The study comprised 137 pediatric patients (mean age, 37.5 months [range, 2.4-167.6 months]) who had moderate (64/137 [46.7%]) or severe (73.137 [53.3%]) mitral valve regurgitation. At midterm follow-up (median, 55.3 months), mitral valve regurgitation had statistically significantly decreased compared with preoperative levels (<i>P</i> < .001, Wilcoxon signed-rank test); freedom from cardiovascular death was 97.5%, and freedom from worsening mitral valve regurgitation was 89.4%. Cox regression analysis identified body weight (<i>P</i> = .02), left ventricular end-diastolic diameter (<i>P</i> = .005), and left ventricular ejection fraction (<i>P</i> = .01) at 1 month and cardiopulmonary bypass time (<i>P</i> = .007) as independent risk factors for deterioration. Patients weighing 10 kg or more (<i>P</i> = .04) or with a ventricular septal defect 8 mm or larger (<i>P</i> = .04) had worse outcomes.</p><p><strong>Conclusion: </strong>Mitral valvuloplasty resulted in low mortality and positive long-term results in pediatric patients with mitral valve regurgitation.
