The first three images show the narrowing of the lumen caused by haematoma compression, whereas the last three images show normal blood vessels. The IVUS catheter (asterisk) was withdrawn from the distal end of the LAD, and the IVUS catheter was located in the true lumen of the blood vessel. Spiral dissection with haematoma could be seen in the distal segment of LAD, while the proximal and middle vessels were normal. No atherosclerotic plaque was seen. The red arrow in the picture shows spiral dissection with haematoma, involving 5:00 to 10:00, 6:00 to 12:00, and 8:00 to 3:00, respectively, and the yellow arrow shows spiral dissection. The blue arrow shows the myocardial bridge
