Transseptal catheterization
Transseptal catheterization through the atrial septum has become a useful skill for electrophysiologists. The challenge for a successful transseptal puncture is positioning the Brockenbrough needle at the thinnest aspect of the atrial septum, the membranous fossa ovalis, guided by either intracardiac echocardiography (ICE) or fluoroscopy.1–5 This article describes the technical aspects of performing a transseptal puncture using ICE and fluoroscopic guidance.
