为评价心导管及心血管造影检查对小儿主动脉狭窄的诊断价值,应用左右心导管检测心室和大血管压力及血氧饱和度,左、右室及升主动脉造影显示狭窄部位和合并畸形,并以造影与超声心动图检查作比较。结果:主动脉瓣上狭窄25例,8例伴有外周体循环动脉狭窄,16例伴有外周肺动脉狭窄,3例存在冠状动脉病变;主动脉瓣狭窄43例,18例单纯主动脉瓣狭窄行球囊瓣膜成形术;主动脉瓣下狭窄48例,46例合并其他先天性心脏病,仅2例为单纯主动脉瓣下狭窄。说明先天性主动脉瓣上及瓣膜狭窄时心导管及心血管造影仍很有必要,单纯主动脉瓣下狭窄,可不必作心导管和心血管造影。
To evaluate the diagnostic value of cardiac catheterization and cardiovascular angiography in pediatric aortic stenosis, left and right cardiac catheterization was used to detect ventricular and macrovascular pressure and oxygen saturation, left and right ventricle and ascending aorta angiography showed stenosis and combined deformity, And contrast and echocardiography for comparison. Results: 25 cases of aortic stenosis, 8 cases of peripheral artery stenosis, 16 cases of peripheral pulmonary stenosis, 3 cases of coronary artery lesions; aortic stenosis in 43 cases, 18 cases of simple aortic stenosis ball Valvular valvuloplasty; 48 cases of aortic stenosis, 46 cases with other congenital heart disease, only 2 cases of simple aortic stenosis. Description of congenital aortic valve and valve stenosis, cardiac catheterization and cardiovascular angiography is still necessary, simple aortic valve stenosis, may not have to do for cardiac catheterization and cardiovascular angiography.
