【摘要】：正患兒男,11歲。自幼發(fā)現(xiàn)心臟雜音。胸骨左緣2、3、4肋間聞及3/6級(jí)粗糙的收縮期雜音。超聲心動(dòng)圖顯示:主動(dòng)脈前壁與室間隔連續(xù)性中斷(最大處24mm,位于嵴下),室水平見(jiàn)雙向低速分流信號(hào)。主動(dòng)脈騎跨率約45%(圖1a)。右室流出道中遠(yuǎn)段變窄,肺動(dòng)脈瓣略增厚,開(kāi)放受限,峰值流速3.9m/s,壓差64mm Hg。主肺動(dòng)脈內(nèi)徑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,
