TI  - Percutaneous transvenous mitral commissurotomy using an Inoue balloon in children 
      with rheumatic mitral stenosis.
PG  - 19-22
AB  - Percutaneous transvenous mitral commissurotomy (PTMC) using the Inoue technique 
      was performed in 557 patients with rheumatic mitral stenosis. Of these, 107 were 
      children aged 10-18 years (mean +/- SD 14.5 +/- 2.3). All patients were 
      symptomatic New York Heart Association (NYHA) Class II (n = 78) and Class III (n 
      = 29). All were in sinus rhythm. Following PTMC, the mitral valve area (MVA) 
      increased from 0.73 +/- 0.18 to 1.7 +/- 0.53 cm2 (P < 0.001). There was a 
      significant fall in mean transmitral gradient from 15.6 +/- 5.2 to 5.1 +/- 2.3 
      mmHg, and in mean pulmonary artery pressure from 41 +/- 15 to 28.4 +/- 10 (P < 
      0.001). Cardiac tamponade developed in one patient. One patient developed severe 
      mitral regurgitation requiring emergency mitral valve replacement. Five patients 
      (4.7%) developed moderate mitral regurgitation. There was no mortality or 
      cerebral embolism in any of the children. Four patients (3.7%) had oximetry 
      evidence of atrial septal defect. Mean mitral valve area and transmitral gradient 
      at 14 months mean follow up was 1.68 +/- 0.4 cm2 and 6 +/- 3.5 mmHg, 
      respectively, and were comparable to the immediate post-PTMC results. Two 
      patients (1.8%) developed restenosis. The immediate haemodynamic results in 
      children were compared to 450 adult patients who underwent PTMC in the same 
      period. The outcome was similar in both groups. Children were found to have 
      significantly higher pulmonary artery pressure compared to adults. We found that 
      PTMC using an Inoue balloon is very effective and safe in children, and consider 
      that it should be the procedure of choice for young patients with symptomatic 
      rheumatic mitral stenosis.
