Successful balloon mitral commissurotomy in a small child: Use of small Inoue balloon catheter

Abstract A 15-month-old girl weighing 5.8 kg, in whom congestive heart failure developed due to congenital mitral stenosis, was successfully treated by percutaneous transluminal mitral commissurotomy using a small Inoue balloon catheter. Percutaneous transluminal mitral commissurotomy using a small Inoue balloon catheter may be a first-choice treatment for small children with congenital mitral stenosis.
