Postoperative angiocardiographic findings were examined in eight patients whose pulmonary artery was reconstructed using an aortic or pulmonary homograft with valve. Apparent dilatation of the outflow tract of the right ventricle was seen in three patients. Only four showed valve mobility, with function judged almost normal in two of them. Calcification in a valve was not seen. The pulmonary trunk showed three directional patters, and stenosis was clearly observed in two cases. calcification of the pulmonary trunk was seen in only one case. The most difficult problem in the reconstruction of the pulmonary artery is the high incidence of pulmonary stenosis.
对8例使用带瓣主动脉或肺动脉同种异体移植物重建肺动脉的患者进行了术后心血管造影检查。3例患者出现右心室流出道明显扩张。只有4例显示瓣膜活动，其中2例功能判断基本正常。未发现瓣膜钙化。肺动脉主干呈现三种走向模式，2例明显观察到狭窄。仅1例出现肺动脉主干钙化。肺动脉重建中最困难的问题是肺动脉狭窄的高发生率。
