Foreword yocardial revascularization has been one of the most important aspects of the management of myocardial ischemia in patients with coronary artery disease. The determination of whether the extent of reduction of coronary blood flow is appropriate to account for the production of myocardial ischemia has become an integral part of the performance of myocardial revascularization. Techniques have been developed to do this in the cardiac catheterization laboratory. In this current issue of the journal, Mark J. Ricciardi, MD, who is an excellent interventionalist, has provided a superb overview of this important procedure. He and his colleagues have described the coronary physiology, methods of measurement of coronary blood flow, and its value in clinical decision making. David P. Faxon,* MD, who is a highly experienced cardiologist and who is widely recognized as one of “The Interventionalists” in this field, has provided a superior insight into this procedure and its value. The Editorial Board and I are very grateful to all of them for this superior issue.
