BACKGROUND: Recent emphasis on the judicious use of imaging prompted the publication of the 2007 ACC/ASE Appropriateness Use Criteria (AUC) for Echocardiography. However, the intersection of the AUC with the safety and clinical use of transesophageal echocardiography (TEE) is not well established. METHODS: We reviewed 490 consecutive orders for TEEs for appropriateness, significant findings, and reasons for cancellation. RESULTS: We found that 79% (389/490) of ordered studies were performed and 21% (101/490) were not. The number of TEEs cancelled for safety reasons (n = 29) was similar to that cancelled for inappropriateness (n = 36). Only 2% (6/389) of those performed were inappropriate vs. 16% of those that were cancelled. New or unsuspected findings were obtained in half of all performed TEEs; the majority of which were ordered to detect cardiac source of embolism (CSE). CONCLUSIONS: The AUC should specifically consider the utility of clinician-based prescreening of TEEs to encourage appropriate use and safety. Furthermore, given the incremental value of TEE over transthoracic echocardiography in detection of CSE, in some cases, TEE may be considered an appropriate initial test for this indication.
