Functional Evaluation of Non Culprit Lesions in ACS Patients Clinical Trial
The assessment of non-culprit stenoses is an important issue in ACS. Adenosine
administration is currently required for functional evaluation of stenosis severity using
the fractional flow reserve (FFR). An alternative adenosine-independent index of coronary
stenosis, the instantaneous wave-free ratio (iFR), was recently introduced.
Aim of the present study will be to evaluate the trans-stenotic instantaneous wave-free
pressure gradient (iFG), the instantaneous wave-free ratio (iFR) and the fractional flow
reserve (FFR) in ACS patients.
