Considerations for the Use of Intracardiac Echocardiography in Cardiac Arrest.

The use of transthoracic echocardiography (TTE) is common during cardiopulmonary resuscitation (CPR) from cardiac arrest, but logistic and practical challenges of obtaining satisfactory images without sacrificing the quality of CPR have resulted in some centers utilizing transesophageal echocardiography (TEE) during CPR. Although TEE avoids many of the downsides of TTE, several challenges exist in routine deployment. An alternative approach, intracardiac echocardiography (ICE), is routinely used by electrophysiologists during regular cardiac electrophysiologic procedures, such as atrial ablation for the treatment of atrial fibrillation.
