Measurement of fractional flow reserve in a patient with combined myocardial bridging and coronary fixed stenosis

A segment of coronary arteries traveling through the myocardium is known as myocardial bridging. Several reports have shown reduced fractional flow reserve (FFR) associated with myocardial bridging. We report a case in which FFR was measured in the left anterior descending artery involving both myocardial bridging and fixed stenosis. <Learning objective: We demonstrated a case in which fractional flow reserve (FFR) was measured in the left anterior descending artery involving both myocardial bridging and fixed stenosis. Measurement of FFR was useful to guide PCI for the lesion modified by myocardial bridging.>.
