The assessment of Left Main Coronary Artery (LMCA) lesions by means of coronary angiography renders serious limitations. Studies with a limited number of patients have shown that a value of FFR (Fractional Flow Reserve) above 0.80 identify a low risk of events in case of not performing revascularization in patients with intermediate stenosis in the LMCA. Although iFR (Instant wave Free Ratio) has recently been found equivalent to FFR The demonstration of the prognostic utility of iFR in patients with LMCA intermediate lesions could have an important clinical impact and justify its systematic use for the treatment decision in these high-risk patients.
