The objectives of this study were to review the efficacy of percutaneous transvenous mitral commissurotomy (PTMC) in young children less than 12 years of age and to provide intermediate‐term follow‐up data. There is a paucity of information regarding the long‐term efficacy of PTMC done in children less than 12 years of age. The data of 100 consecutive children less than 12 years of age (mean, 11.1 ± 1.2 years) who underwent PTMC using Inoue balloon were analyzed retrospectively. Serial clinical and echocardiographic follow‐up information of more than 6 months was available in 94 patients. The procedure was successful in 94 patients. The mean calculated mitral valve area (MVA) increased from 0.72 0.14 to 1.7 0.35 cm 2 ( P 0.0001). Echocardiographic restenosis (MVA ≤ 1 cm 2 or > 50% gain loss) occurred in 14 of 94 patients (16%) over a mean follow‐up of 34.4 25.9 (range, 2–115) months. The improvement in New York Heart Association (NYHA) functional class was maintained in most patients (from a mean of 2.87 0.5 pre‐PTMC to 1.42 0.6 at follow‐up). Seven out of 14 patients with restenosis underwent a re‐PTMC. The actuarial rate of good functional status (survival, no repeat interventions, and NYHA class 1 or 2) at 100 months was 75.4% 8.7%. PTMC provides excellent intermediate‐term palliation even in young children with rheumatic mitral stenosis. Catheter Cardiovasc Interv 2005;64:487–490. © 2005 Wiley‐Liss, Inc.
