Myocardial perfusion studies by contrast echocardiography.
Determination of regional myocardial blood flow may provide clinically valuable information about ischemia, risk area, and the effect of angioplastic, surgical, and pharmacologic interventions. Contrast echocardiography, with use of prepared microbubbles of 4 to 8 microns size, graphically demonstrates perfusion characteristics in the catheterization laboratory. Analysis and interpretation of this data and the creation of contrast materials that will demonstrate myocardial perfusion after intravenous injection are some of the next challenges in these techniques.
