Objective: to provide anatomic basis for choosing a donator with a suitable pulmonary artery diameter with receptor during extension of congenital pulmonicstenosis 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
P2 may be augmented in pulmonary hypertension and diminished in pulmonicstenosis.
肺动脉高血压可加剧P2，肺动脉瓣狭窄时则P 2减轻。
3
Objective: to improve the diagnostic rate of pulmonicstenosis using two dimensional and Doppler echocardiography and to reduce the rate of misdiagnosis.
