摘要
对16例先天性肺动脉瓣狭窄病人行经皮球囊肺动脉瓣成形术(PBPV),在PBPV前后行二维及彩色多普勒血流显像和连续式多普勒超声心动图检查。用连续式多普勒探测肺动脉瓣最大瞬时压差、平均压差及瓣口面积,并与心导管相应测值比较,相关系数分别为0.94、0.95、0.90(P<0.001)。表明连续式多普勒能准确定量肺动脉瓣狭窄程度及反映PBPV前后压差和瓣口面积的变化。将测得之动脉瓣环直径和二维超声值与右室电影造影测得值相比,亦示相关密切(r=0.92,P<0.001)。
Percutaneous balloon pulmonary valvuloplasty(PBPV)was used
in the treatment of congenital pulmonary valve stenosis in 16 patients.Color
Doppler flow imaging and continuous wave Doppler(CWD)echocardiography
were performed before and after PBPV.It is highly significant that the
correlation among the instant peak pressure gradient,mean pressure gradient,
the area of pulmonary orifice measured by CWD and those by catheterization
(γ=0.94,0.95,0.90,P<0.001).The results demonstrate that CWD can
quantitate the severity of pulmonary valve stenosis and reveal changes in
pressure gradient and area of orifice before and after PBPV.There was
significant linear correlation between anulus diameter measured by two-
dimensional echocardiography and that by the right ventricular angiogram.
