Clinical application of the first pediatric appropriate use criteria (AUC) for transthoracic echocardiography (TTE) is feasible and found most pediatric TTE to be appropriate, according to a study recently published in the Journal of the American College of Cardiology. Overall, 85 percent of TTEs were normal. Of the top three TTE appropriate indications, pathologic murmur had the highest yield of abnormal findings and exertional chest pain had the lowest. The authors conclude that the findings of this study show that educational interventions may reduce the use of TTE for rarely appropriate indications. Moving forward, future studies should evaluate the change in patient care and outcomes as a result of the AUC. Read more on ACC.org.
