Balloon mitral commissurotomy
Percutaneous balloon mitral commissurotomy using the Inoue balloon. This device is a modification of a simple cylindrical balloon, waisted to hold its position in the stenotic mitral orifice (1). Using transseptal access, as seen here, the balloon is positioned across the orifice and expanded until an adequate mitral orifice is created with a minimum of regurgitation. The procedure is usually done under fluoroscopic guidance, but may be done under TEE or intracardiac echocardiographic guidance (2). It is especially useful in young, pliable valves (3) and during pregnancy (4). Early results predict late results (5).
