用一根顶端带有气囊的特殊的导管在房间隔(左心房和右心房之间的壁)上造一个口。
A special catheter with a balloon in the tip is used to create or enlarge an opening in the atrial septum (wall between the left and right atria).
目的观察房间隔缺损(asd)经右心导管行封堵术后，右心房(RA)、右心室(RV)形态及功能的变化。
Objective To observe the shape and function changes of right atrium (ra) and right ventricle (rv) after closure ASD in transcatheter.
结论：食管左心房压迹定房间隔穿刺点，方法准确安全，简单易行。
Conclusion: The new method of atrial septal puncture located by left atrial impression on esophagus is accurate, safe and simple to perform.
结果心房的容量负荷和压力负荷增加时，房间隔的厚度增加、运动速度增快或减慢。
Results With increase of the volume load and pressure load in the atrium, the atrial septal thickness increased, and the velocity of atrial septal motion increased or reduced.
目的观察右心耳及房间隔起搏对心房电活动的影响。
Objective To observe effects of right atrial appendage (RAA) pacing and atrial septal (AS) pacing on atrial activation.
结论：高龄本身并非老年房间隔缺损手术禁忌，老年患者通过封堵器或手术闭合房缺仍可以重构右心房、右心室，降低肺动脉压，显著改善心功能。
Closure of the ASD can still remodel the right atrium and ventricular, decrease the pulmonary artery pressure, and improve the cardiac function in the elderly patients.
经房间隔穿刺，放置左心房导管。
The ablation catheter was placed in left atrium by transeptal access.
房间隔缺损不产生明显心脏杂音，因为心房之间压力差很小。
An atrial septal defect is unlikely to produce a loud murmur because of the minimal pressure differential between the atria.
部分心房肌细胞不含有免疫反应颗粒，主要位于左房背侧壁、房间隔和冠状窦等部位。
Parts of atrial muscle cells which were distributed in the back of the left atrium, a...
