肺动脉瓣狭窄(以下简称PS)的经皮球囊扩张术(PTPV)于1982年由Kan.J S 首次报告后在美国已普及,作者从1984年对10例PS 用PTPV 法进行治疗,除1例外均获成功。对象及方法年龄20月～13岁,平均5岁,男6例,女4例。首先用超声心动图检查测定肺动脉瓣环径,通过右心导管检查测定肺动脉压,右室压以及肺动脉和右心室压力差。然后通过右室电影造影观察肺动脉瓣的形态、运动以及瓣环直径,并用热稀释法测定心排量。以后再从左侧股动脉和股静脉插入导管,监测
Percutaneous balloon dilatation (PTPV) of pulmonary valve stenosis (hereinafter referred to as PS) was first reported in the United States in 1982 by Kan.JS. The authors treated 10 P PSV patients with PTPV in 1984 except one All succeeded. Subjects and methods Aged 20 months to 13 years old, average 5 years old, 6 males and 4 females. Pulmonary valve annulus diameter was measured by echocardiography and pulmonary arterial pressure, right ventricular pressure, and pulmonary artery and right ventricular pressure were measured by right heart catheterization. The morphology, motion, and annulus diameter of the pulmonary valve were observed by contrast-enhanced radiography of the right ventricle and the cardiac output was measured by thermal dilution. Later from the left femoral artery and femoral vein catheterization, monitoring
