Figure 1
Figure 1 Electrocardiogram showed ST-segment elevation myocardial infarction.
Figure 2
Figure 2 Myocardial bridging was identified on coronary angiography. A and B: Myocardial bridging (rectangle) was stenosed about 90% during systole and recovered during diastole on January 14, 2020; C and D: The myocardial bridging (white arrow) was stenosed about 30% on October 13, 2020, and its length was reduced during follow-up.
Figure 3
Figure 3 Intravascular ultrasound showed myocardial bridging. There was no obvious change of the lumen area during systole during follow-up. A and B: An apparent ‘half-moon’ phenomenon of the myocardial bridging on October 13, 2020 (yellow arrow); C and D: The vascular lumen area of the mural coronary artery was 5.10 mm2 during diastole and 4.97 mm2 during systole.
