*According to the AHA scientific statement, TEE is preferred over TTE, but the latter should be performed if TEE is not immediately available. TTE may be sufficient in small children
†AHA statement also suggests TEE as first-line test in patients with a prosthetic valve and suspected IE
‡In this clinical scenario, the AHA statement recommends repeating the TEE in 3 to 5 days or sooner
§ESC guidelines stipulate that the timing and mode (TTE or TEE) of repeat test depend on initial findings, microorganism type, and initial response to therapy
