[Percutaneous mitral commissurotomy with an Inoue catheter in congenital mitral stenosis].
We describe a 3-years-old boy, with congenital mitral stenosis, who underwent percutaneous transvenous mitral commissurotomy (PTMC) with Inoue balloon. The mitral gradient decreased from 24 to 4 mmHg, the mitral valvular area (MVA) increased from 1.2 to 1.6 cm2 without modification in mitral regurgitation. One year later the recatheterization showed decreased pulmonary pressures, and a 7.5 mmHg mitral valvular gradient without mitral insufficiency. MVA by echo is 1.8 cm2 with mild regurgitation. As far as we know there is no experience with Inoue balloon in children. We conclude that PTMC with Inoue balloon could be an attractive alternative in some patients with congenital mitral stenosis.
