近期,我们对47例先心病患儿在行右心导管检查的同时作左心声学造影,初步探讨其对左→右分流先心病的诊断价值,现报告如下。一、检查方法均在局麻下经皮穿刺经股静脉行右心导管检查。所用导管为6～7F普通右心导管或漂浮导管。于各心腔常规测血氧及压力、探查有无异常通道,然后将导管尖端插入肺 Recently, 47 cases of congenital heart disease in children undergoing right heart catheterization at the same time for left ventricular angiography, preliminary study of its diagnostic value of left → right shunt congenital heart disease, are as follows. First, the test methods are under local anesthesia percutaneous puncture via the right ventricle catheter check. The catheter used is 6 ~ 7F common right heart catheter or floating catheter. Blood oxygen and pressure were routinely measured in each heart chamber to detect whether there was an abnormal passage and then the catheter tip was inserted into the lung
