Advances in myocardial contrast echocardiography and the role of adenosine stress

Advances in contrast echocardiography hold promise for the routine assessment of myocardial perfusion. Continued progress may ultimately position myocardial contrast echocardiography (MCE) as an imaging modality that can provide comprehensive cardiac assessment-anatomic, physiologic, and pathophysiologic. Vasodilator stress with adenosine can play an important role in conjunction with MCE, particularly as it relates to the noninvasive evaluation of myocardial perfusion and coronary blood flow reserve. Adenosine pharmacologic stress testing may provide improved test performance through perfusion detection when compared with traditional use of dobutamine assessments of regional wall motion abnormalities.
