【摘要】：正患儿男,11岁。自幼发现心脏杂音。胸骨左缘2、3、4肋间闻及3/6级粗糙的收缩期杂音。超声心动图显示:主动脉前壁与室间隔连续性中断(最大处24mm,位于嵴下),室水平见双向低速分流信号。主动脉骑跨率约45%(图1a)。右室流出道中远段变窄,肺动脉瓣略增厚,开放受限,峰值流速3.9m/s,压差64mm Hg。主肺动脉内径15.0mm,左、
[Abstract]:A 11-year-old male was diagnosed with cardiac murmur at an early age. The left sternum 2, 3, 4 intercostal and 3/6 grade coarse systolic murmur were detected. Echocardiography showed that the continuity between the anterior wall of the aorta and the interventricular septum was interrupted (maximum 24mm, located in the subcristal canal, ventricular water). Bidirectional low velocity shunt signal was seen in both directions. The aortic straddle rate was about 45% (fig. 1 a). The middle and distal segments of the right ventricular outflow tract became narrower. Pulmonary valve was slightly thickened, open was limited, peak velocity was 3.9 m / s, pressure difference was 64 mm Hg, diameter of main pulmonary artery was 15.0 mm, left,
