Since 1960 31 children, 2-10 years old, with large ventricular septal defects and pulmonary arterial hypertension, underwent pulmonary artery banding in Munich. 22 of these children were recatheterized 3-5 years after the operation. Only 8 of these children were shown to have a definite decrease in pressure distal to the band, and in only 2 of these children a reduction of pulmonary vascular resistance to values at the upper limit of normal could be shown. In the remaining children either little or no alteration and rarely even a definite increase of pulmonary vascular resistance was found. There was only a poor correlation between pressure changes and resistance changes. During preoperative catheterization oxygen breathing was shown to produce a more than 50% reduction in the pulmonary arterial pressure in 8 cases. Of these, only 5 showed a decrease of pulmonary vascular resistance after pulmonary artery banding. This decrease, however, was relatively small.
自1960年以来，慕尼黑有31名2至10岁患有大型室间隔缺损和肺动脉高压的儿童接受了肺动脉环扎术。其中22名儿童在术后3至5年接受了再次心导管检查。这些儿童中只有8名显示环扎远端压力有明确下降，只有2名儿童的肺血管阻力降低至正常上限值。在其余儿童中，要么肺血管阻力几乎没有变化，要么没有变化，甚至很少有明确增加的情况。压力变化与阻力变化之间的相关性很差。术前心导管检查期间，8例患者吸氧后肺动脉压降低超过50%。其中，只有5例在肺动脉环扎术后肺血管阻力降低。然而，这种降低相对较小。
