title: Myocardial perfusion: contrast echocardiography perspectives.
abstract: Contrast echocardiography may become a useful means of quantifying transmural regional myocardial perfusion patterns, experimentally and clinically, in a variety of settings. Contrast echocardiography has already been used in the operating room to study perfusion during coronary artery bypass graft (CABG) surgery. Other recent studies have demonstrated the ability of contrast echocardiography to predict wall motion improvement following acute myocardial infarction and therapeutic intervention. This is significant in the light of the discrepancy that has recently been shown between epicardial coronary vessel diameter and coronary flow. Studies suggest that both tissue and blood flow and volume may be quantitatively evaluated using contrast echocardiography, and these parameters ultimately may be used to assess tissue viability or vascular reserve. Contrast echocardiography techniques have been shown to be safe and reliable, and provide a high degree of spatial and temporal resolution.
