Intracardiac Echocardiographic Guidance for Structural Heart Procedures: Current Utility as Compared to Transesophageal Echocardiography.

Over the past decade, engineering advances in intracardiac echocardiography (ICE) have improved the ability of an imager or interventionalist to guide not only interatrial septal procedures but now commonly left atrial appendage, tricuspid, and mitral procedures. When transesophageal echocardiography (TEE) is not possible because of anatomic limitations, ICE has proved a useful tool to safely complete structural interventions. ICE will play a growing, key role in structural interventions where anatomic factors strongly favor an intracardiac perspective or augment TEE when imaging is suboptimal.
