A focus on intracardiac echocardiography (ICE), with an emphasis on practical use during electrophysiological procedures.This illustrated text, complemented by over 50 instructional videos, presents description, rationale, and instruction in ICE utilization for the complete range of currently performed EP procedures, including mapping and ablation procedures, device implantation procedures, and all common variations on these procedures. ICE is the only continuous real-time imaging modality with widespread utilization by electrophysiologists: Reliably and accurately visualize intracardiac and extracardiac structures and placement of catheters within the heart chambers.Observe anatomic detail otherwise invisible.Potentially improve procedural safety and efficacy.This text is written and edited by experts with extensive experience and knowledge that they have imparted to the reader. The editors have previously collaborated on a related textbook from Cardiotext Publishing, Fluoroscopy Reduction Techniques for Catheter Ablation of Cardiac Arrhythmias.
