Answer

The AHA 2010 guideline update on CIED infections recommends TEE to evaluate the left-sided heart valves for all adults suspected of having CIED-related endocarditis, even if TTE has shown lead-adherent masses. If TTE views are good, TTE may be sufficient for pediatric patients. Patients with positive blood culture results or negative blood culture results taken after recent antimicrobial therapy should undergo TEE for CIED infection or valvular endocarditis. [43]

Visible vegetation suggests a worse prognosis. Both TTE and TEE are highly specific for valvular vegetations; however, sensitivity differs.
