Difficult percutaneous transvenous mitral commissurotomy: a new technique for left atrium to left ventricular entry.

ABSTRACT

Percutaneous transvenous mitral commissurotomy using Inoue balloon is an effective procedure for the management of patients with juvenile mitral stenosis. Inability to cross the mitral valve by the Inoue balloon catheter is one of the important reasons for failure of the procedure. We describe a new technique, facilitating left atrium to left ventricular entry using double loop of Inoue balloon catheter in a child with small left atrium.
