病例1患者男,30岁,心悸半年。超声显示:左冠状动脉起始段内径增宽达9.1mm,前降支与室间隔及心尖肌小梁部丰富的五彩镶嵌血流信号相通,部分血流信号与右室间似可见左向右分流。主动脉右冠窦内未见冠状动脉开口,主肺动脉内侧壁见一宽约5.6mm的管状结构发出,经升主动脉前方向右走行(图1),其内可检出舒张期为主的双期血流信号进入主肺动脉,峰值流速约1.4m/s(图2)。右心超声造
Case 1 patient male, 30 years old, palpitations for six months. Ultrasonography showed that the diameter of the left coronary artery increased 9.1 mm in diameter. The anterior descending branch was interlinked with the multicolored mosaic blood flow signals of the interventricular septum and apical trabeculae. Some of the blood flow signals showed left-to-right Shunt. Aortic sinus right coronary sinus no openings, the main pulmonary artery medial wall to see a wide tubular structure of 5.6mm issued through the ascending aorta to the right before the line (Figure 1), which can be detected within the diastolic Two-phase flow into the main pulmonary artery signal, the peak flow rate of about 1.4m / s (Figure 2). Right heart ultrasound made
