Imaging during percutaneous mitral balloon commissurotomy. (A) The intracardiac echocardiography (ICE) image on the left shows the mitral valve and the fully inflated balloon. (B) The fluoroscopic image on the right shows the indented midsection of the valve from the fused commissures immediately before full inflation splits the scar tissue and relieves the obstruction.
