The researcher will be involved in the conduction of a study focusing on the physiologic assessment of myocardial bridges (MBs) with a new diastolic specific index, the instantaneous wave-free ratio (iFR). The term MB refers to a band of muscle overlying a segment of the epicardial coronary artery, usually referred as tunneled artery. This condition may occasionally present with stable angina, acute coronary syndromes, Takotsubo syndrome, and malignant arrhythmias. In this scenario, adequate identification of a MB with hemodynamic relevance is of paramount importance to guide therapy and avoid unnecessary interventions. The fractional flow reserve index, although accepted as the gold standard for assessment of fixed coronary lesions, is inadequate for assessment of the hemodynamic significance of a MB. Thus, the study aims to compare the use of traditional FFR with the diastolic specific index iFR for the physiological evaluation of MBs.
