Tremendous advances in intracardiac echocardiography (ICE) have coincided with the evolution of interventional electrophysiology. This book is designed to provide both the electrophysiologist and echocardiographer with an in-depth view of the role and value of ICE during electrophysiologic procedures. A guide to techniques used for optimal ICE imaging in cardiac electrophysiology is provided. In addition, new and less-recognized uses of ICE in electrophysiological procedures are described and their clinical applications are presented. Illustrated with over 500 images, many of which are in color, the book can also be used as a practical atlas. Readers need not be experts in the field of echocardiography to benefit from this practical approach to intracardiac imaging in electrophysiology.
