1·Objective: to provide anatomic basis for choosing a donator with a suitable pulmonary artery diameter with receptor during extension of congenital pulmonic stenosis and lung transplantation.
目的：为先天性肺动脉狭窄扩张术和肺移植术选择与受体肺动脉直径相配的供体提供解剖学基础。
2·The most common causes are aortic or pulmonic valve regurgitation.
最常见的原因是主动脉瓣或肺动脉瓣反流。
3·The P wave changes had certain relations with lowering of pulmonic mean pressure.
波的改变可能与肺动脉平均压下降有关。
4·When the spiral septum fails to completely descend, the aortic and pulmonic trunks are left undivided at their outflow.
一旦螺旋形隔板下降不全，主动脉和肺动脉干的血流将不能分开。
5·P2 may be augmented in pulmonary hypertension and diminished in pulmonic stenosis.
肺动脉高血压可加剧P2，肺动脉瓣狭窄时则P 2减轻。
