“Estimation of Mean Left Atrial Pressure in Patients with Acute Coronary Syndromes: A Doppler Echocardiographic and Cardiac Catheterization Study”
CME Information: 1.5 credits
Release date: March 2019 Valid through: March 2020
Introduction/Statement of Need:
Doppler echocardiography, including the ratio of transmitral E to tissue Doppler e0 velocities (E/e0), is widely used to estimate mean left atrial pressure (mLAP). This method, however, has not been validated in patients with acute coronary syndromes. In patients with acute coronary syndromes, Doppler- and catheter-derived estimates of mLAP correlate well in patients with reduced EFs. In the acute setting, echocardiographic evaluation is a reliable adjunct to clinical examination in assessment of heart failure in this subgroup of patients. (J Am Soc Echocardiogr 2018)
This activity is designed for all cardiac sonographers and cardiovascular physicians with a primary interest and knowledge base in the field of echocardiography; in addition, residents, researchers, clinicians, intensivists, and other medical professionals.
At the end of this article the reader will better be able to:
Describe the various Doppler calculations used for noninvasive estimation of left atrial pressure
Analyze the relative advantages of Doppler echocardiography in assessing LA pressure in acute coronary syndromes
Detail the differences in estimating LA pressure by Doppler echo in ACS patients with normal versus reduced ejection fraction

The American Society of Echocardiography designates this enduring material for a maximum of X AMA PRA Category 1 CreditsTM. Physicians should claim only the credit commensurate with the extent of their participation in the activity.
Successful completion of this CME activity, which includes participation in the evaluation component, enables the participant to earn up to X MOC point in the American Board of Internal Medicine's (ABIM). Participants will earn MOC points equivalent to the amount of CME credits claimed for the activity. It is the CME activity provider's responsibility to submit participant completion information to ACCME for the purpose of granting ABIM MOC credit.
ARDMS, CCI and Sonography Canada recognize ASE’s certificates and have agreed to honor the credit hours toward their registry requirements for sonographers.
