本文报道球囊扩张瓣膜成形术治疗先天性肺动脉症狭窄(CVPS)的效果,着重讨论心电图,心电向量图及多普勒超声心动图在估计残余梗阻方面的价值。方法:1982～1984年间,19例 CVPS 患儿,平均年龄4.5±4.6岁(5个月～18岁)。在胸骨左缘上方可闻及4～5/6级收缩期喷射性杂音计17例,返流性杂音仅1倒。经皮穿刺右侧股静脉和股动脉,插入2支右心导管和1支左心导管。所用导管的球 This article reports the results of balloon valvuloplasty in the treatment of congenital pulmonary stenosis (CVPS), focusing on the value of electrocardiogram, electrocardiogram and Doppler echocardiography in the estimation of residual obstruction. Methods: Between 1982 and 1984, 19 children with CVPS averaged 4.5 ± 4.6 years (range, 5 months to 18 years). On the left side of the sternum can smell the 4 ~ 5/6 systolic jet murmur in 17 cases, only one down reflux murmur. Percutaneous right femoral vein and femoral artery, insert two right heart catheter and a left cardiac catheterization. Catheter ball used
