چکیده

The contrast agents used in ultrasound are approved for several clinical situations. New echocardiographic techniques, such as harmonic imaging and power pulse inversion imaging, can improve the visualization of microbubbles. In this article we discuss the early development of contrast echocardiography, new technologies that help improve image acquisition and its practical role in the assessment of myocardial infarction.

Usefulness of quantitative intravenous myocardial contrast echocardiography to analyze microvasculature perfusion in patients with a recent myocardial infarction and an open infarct-related artery: comparison with intracoronary myocardial contrast echocardiography.

AIMS We analyzed the usefulness of quantitative intravenous myocardial contrast echocardiography to study microvasculature perfusion after infarction in comparison with intracoronary myocardial contrast echocardiography. METHODS AND RESULTS Thirty-two patients with a first ST elevation myocardial infarction, single-vessel disease and an open artery (TIMI 3) were studied before discharge. Myoc...

Combined assessment of reflow and collateral blood flow by myocardial contrast echocardiography after acute reperfused myocardial infarction.

OBJECTIVE To evaluate the combined assessment of reflow and collateral blood flow by myocardial contrast echocardiography after myocardial infarction. DESIGN Myocardial contrast echocardiography was performed in patients with acute myocardial infarction shortly after successful coronary reperfusion (TIMI 3 patency) by direct angioplasty. Collateral flow was assessed before coronary angioplast...

Clinicopathological study in an ovine model of experimental acute myocardial infarction

To evaluate the prognostic significance of clinicopathological measurement in the diagnosis of acute myocardial infarction (MI) in sheep, acute MI was induced by ligation of left anterior descending coronary artery (LAD). For this purpose, twenty four healthy sheep were divided into the sham-operated or control group (group I, thoracotomy without MI) and the experimental group (group II, with M...

Contrast Echocardiography

Ultrasound contrast agents are widely used in clinical practice for left ventricle opacification in sub-optimal echocardiograms. Recently, significant research has focused on the use of contrast echocardiography as a non-invasive means to evaluate myocardial perfusion. Advances in contrast agents as well as ultrasound technology have enabled investigations into myocardial contrast echocardiogra...
