Myocardial Contrast Echocardiography

MCE has evolved from a laboratory tool to a clinical procedure. It would be wrong to consider it merely another tool for imaging of myocardial perfusion. As discussed, it allows physicians to bring physiology and pathophysiology to the bedside, providing a better understanding of the underlying mechanisms of abnormal findings in individual patients. MCE can provide quantitative measurements that can be repeated as often as necessary in a patient. Because of its complexity, large clinical studies are necessary to define the role of MCE in the general clinical milieu. Advances in MCE continue at a very rapid pace, and its potential for the study of endothelial function, site-specific targeting, and local delivery of drugs appears promising. Its role will continue to evolve into the early part of the next century. What we learn of the myocardium can be easily applied to other organ systems accessible to ultrasound. The future of MCE appears very exciting.
