Transseptal puncture guided by intracardiac echocardiography during percutaneous transvenous mitral commissurotomy in patients with distorted anatomy of the fossa ovalis.
Positioning of the transseptal needle during percutaneous transvenous mitral commissurotomy (PTMV) can become a difficult and risky procedure when distortion of the interatrial septum exists. We present two cases where intracardiac echocardiography (ICE) facilitated the transseptal puncture in the presence of bulging of the fossa ovalis into the right atrium.
