ClinConnect Summary
Both physiologic information from fractional flow reserve (FFR) and anatomical information from intravascular ultrasound (IVUS) in assessing intermediate coronary stenotic lesions are useful. Functional significance of a coronary stenosis is determined by both the severity of a stenosis and the amount of myocardium supplied. Therefore, when the functional significance of a lesion is assessed by lumen area measured by IVUS, different criteria should be applied according to lesion location and anatomical variations of the coronary artery. However, previous studies included only patients with ...
