Answer

Transthoracic echocardiography helps to assess left ventricular function, wall-motion abnormalities in the setting of ACS or AMI, and mechanical complications of AMI.

Transesophageal echocardiography is most often used for assessing possible aortic dissection in the setting of AMI. Stress echocardiography can be used to evaluate hemodynamically significant stenoses in stable patients who are thought to have CAD. Treadmill echocardiography stress testing and dobutamine echocardiography stress testing provide equivalent predictive values. ECG findings are depicted below.
