摘　　要：用可折叠的双刃导管切割狭窄的肺动脉瓣,可缓解右室排血的受阻。在多次动物实验,证实其可行性和安全性后,即进行临床应用。3例手术前后的右心室压力分别从85,100和120mmHg降至42,60和90mmHg。最后一例年龄13岁,圆锥部狭窄较重,术后造影显示狭窄口已扩张,但右室压力下降不明显,再用球囊导管作瓣口成形术,右室压力降至48mmHg。We deviced a special kind of retractile double blade catheter for splitting the stenotic pulnonary valve in order to get rid of the impedence of the right venfricular outflow. After several animal experiments proved its safety and feasibility, 3 clinical cases were carried out with encouraging results. The right ventrieula pressure lowered from 85, 103, and 120mmHg down to 42, 60, and 90mmHg respectively, The last case aged 13 with serene puhnonary conic stenosis was undergone valvotomy but the right venfrieular pressure did not subside even the radioangiogram showed, no more stenosis. The patient who further treated by baloom catheter valvoplasty with right ventricular pressure down to 48mmHg. After all the donble-blade pulmonary valvotomy might be an atternative or art adjunet to the baloom catheter valvoplasty.
