Comparison of the Clinical Application of the American College of Cardiology Foundation/American Society of Echocardiography Appropriateness Criteria for Outpatient Transthoracic Echocardiography in Academic and Community Practice Settings

However, limitations of the AC for TTE are identified that suggest revisions will be needed to fully encompass and stratify the broad clinical practice of echocardiography.
