先天性心血管异常可致新生儿及婴幼儿的气食道受损。先天性心脏病虽很少压迫新生儿及婴幼儿的主气道,但左心肥大会进一步压迫左主支气管,因气管和左主支气管与左心房、左肺静脉和左肺动脉之间关系密切。如平均肺动脉压(MPAP)、平均左心房压(MLAP)和气管隆凸角增大则主气道压力也增高。本文通过收集25例2月～11岁患儿的心导管检查资料,比较正常人与肺循环量增大和左心房肥大
Congenital cardiovascular abnormalities can cause damage to the airways of newborns and infants. Although congenital heart disease rarely affects the main airway of newborns and infants, left-lean convention further oppresses the left main bronchus because of the close relationship between the trachea and the left main bronchus and the left atrium, left pulmonary vein, and left pulmonary artery. Main airway pressure also increased with mean pulmonary arterial pressure (MPAP), mean left atrial pressure (MLAP), and increased lumen protuberance angle. This article by collecting 25 cases of children from February to 11 years of cardiac catheterization data, compared with normal pulmonary circulation and increased left atrial hypertrophy
