*TEE in the ED is valuable for critically ill patients
*TEE has advanced diagnostic potential, including the identification of aortic dissection in a rare number of cases
*TEE has value in cardiac arrest in particular for its ability to provide all the benefits of echocardiography (identification of reversible causes, prognostication, subjective and objective evaluation of CPR quality) without any need to interrupt chest compressions
