Prevalence and Prognostic Relevance of Modifying Anatomical Features Influencing the Measurement of Fractional Flow Reserve in Complex Situations in Daily Practice

Fractional low reserve (FFR)-guided percutaneous coronary intervention (PCI) has been shown to reduce the need for PCI and to improve clinical outcome. Several anatomical features and hemodynamic parameters are well known to influence FFR determination. We evaluated the prevalence and prognostic impact of modifying anatomical features influencing the FFR- measurement on survival, myocardial infarction and the need of recurrent coronary revascularization.
