September 9, 2009 — The American Society of Echocardiography's Guidelines and Standards Committee and the Task Force on Prosthetic Valves have issued new guidelines for evaluation of prosthetic valves.
The new recommendations, which are published in the September issue of the Journal of the American Society of Echocardiography, were endorsed by 5 professional organizations (the American College of Cardiology Cardiovascular Imaging Committee, Cardiac Imaging Committee of the American Heart Association, the European Association of Echocardiography of the European Society of Cardiology, the Japanese Society of Echocardiography, and the Canadian Society of Echocardiography).
Prosthetic valve dysfunction can cause symptoms that are not easily distinguished from ventricular dysfunction, pulmonary hypertension, and dysfunction of the native valves. Furthermore, echocardiography is more difficult to perform and interpret on prosthetic vs native valves.
This review of echocardiographic and Doppler techniques and recommendations for the evaluation of prosthetic valve function were based on a literature review and consensus of an international panel of experts and endorsed by the American Heart Association, the American College of Cardiology, the European Association of Echocardiography, the Japanese Society of Echocardiography, and the Canadian Society of Echocardiography.
