Video 1: Coronary angiography showing myocardial bridging
Video 2: IVUS demonstrating systolic compression of the mid-LAD with a minimum lumen area oscillating from 3.06 mm2 in systole to 5.02 mm2 in diastole and an echolucent region between the bridged coronary segment and epicardial tissue persisting throughout the cardiac cycle (‘half-moon sign’)
Video 3: Left ventricular (LV) angiography revealing typical mid-apical ballooning with hypercontractility of the basal segments
Video 4: Follow-up Echocardiography illustrating restoration of left ventricular function
