Fractional flow reserve and intravascular ultrasound are supported for routine use to determine stenosis severity and predict event rates in ambiguous left main coronary artery stenosis.
Does the use of fractional flow reserve and intravascular ultrasound improve the assessment of severity and prediction of event rates in patients with ambiguous left main coronary artery stenosis compared to angiography alone?
Routine use of FFR and IVUS is supported by evidence for accurately assessing ambiguous left main coronary artery stenosis, overcoming the limitations of angiography and noninvasive tests.
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.
Leesar et al. (Wed,) conducted a review in Ambiguous left main coronary artery stenosis. Fractional flow reserve and intravascular ultrasound was evaluated. Fractional flow reserve and intravascular ultrasound are supported for routine use to determine stenosis severity and predict event rates in ambiguous left main coronary artery stenosis.
