title: Intravascular imaging and physiologic lesion assessment to define critical coronary stenoses.
abstract: Despite the fact that the coronary angiogram is the gold-standard in assessing a coronary artery stenosis for the purposes of clinical decision making, it has many limitations. Alternative methods are available. This article discusses three of these: intravascular ultrasound, coronary flow reserve, and fractional flow reserve.
