Hemodynamic and intravascular ultrasound assessment of an ambiguous left main coronary artery stenosis.
The assessment of the left main coronary artery (LMCA) stenosis by angiography is not reliable, and noninvasive tests are incapable of discriminating ischemia caused by LMCA versus other stenoses. Among patients with LMCA stenosis, both fractional flow reserve and intravascular ultrasound parameters would determine the severity of stenosis and predict the event rates. This review outlines the evidence in support of their routine use for the assessment of an ambiguous LMCA stenosis.
