Physiologic approach for coronary intervention. The Korean journal of internal medicine Fearon, W. F. 2013; 28 (1): 1-7


When invasively assessing coronary artery disease, the primary goal should be to determine whether the disease is causing a patient's symptoms and whether it is likely to cause future cardiac events. The presence of myocardial ischemia is our best gauge of whether a lesion is responsible for symptoms and likely to result in a future cardiac event. In the catheterization laboratory, fractional flow reserve (FFR) measured with a coronary pressure wire is the reference standard for identifying ischemia-producing lesions. Its spatial resolution is unsurpassed with it not only being vessel-specific, but also lesion-specific. There is now a wealth of data supporting the accuracy of measuring FFR to identify ischemia-producing lesions. FFR-guided percutaneous coronary intervention of these lesions results in improved outcomes and saves resources. Non-hemodynamically significant lesions can be safely managed medically with a low rate of subsequent cardiac events.
