Analysis of the values of hemodynamics and the results of open biopsy of the lung in 60 patients with ventricular septal defect and high-level pulmonary hypertension, as well as the results of surgical treatment of 30 of them showed the expediency of diagnostic open biopsy of the lung in patients of the IIIb hemodynamic group, except for patients whose hemodynamic values range as follows: the ratio of general pulmonary to general peripheral resistance in more than 0.7; the ratio of pulmonary to systemic circulation is less than 1.5; the arteriovenous shunt is less than 25%, and the mean pulmonary artery pressure is above 75 mm Hg, and these hemodynamic values correspond with the morphological changes characteristic of stage IV-V after Heat-Edwards.
对60例室间隔缺损合并重度肺动脉高压患者的血流动力学值及肺开放活检结果进行分析，并对其中30例患者的手术治疗结果进行分析，结果表明，对于血流动力学IIIb组患者，除血流动力学值如下的患者外，进行诊断性肺开放活检是合适的：总肺阻力与总外周阻力之比大于0.7；肺循环与体循环之比小于1.5；动静脉分流小于25%，且平均肺动脉压高于75 mmHg，这些血流动力学值与Heat-Edwards法IV-V期的形态学变化特征相符。
