Methods Three various approaches, the mitral valve exposing approach with DAA, the transseptal approach through right atrium and the left atrial approach through interatrial sulcus, were carried on ten free adult cadaver hearts, and the length of these three approaches were measured and compared. 方法以解剖学的方法,于10个离体成人心脏上模拟升主动脉后二尖瓣显露切口、经右心房-房间隔切口和经房间沟-左心房切口,对三种切口的长度进行测量并比较。
Conclusions TEE is useful in RFCA procedures under local anesthesia for guiding transseptal procedure, helping the proper position of ablation and coronary sinus catheters, and detecting complications in early stage. 结论在RFCA术中行TEE监测有助于电极的定位和防止电极脱位,及时发现并发症,引导冠状窦电极放置和穿房间隔消融。
The diastolic transseptal pressure gradient correlated inversely with the eccentric index. 跨室间隔压力差与左室舒张末偏心指数呈显著负相关。
Material and Method: ASD models were established by transseptal pucture and balloon dilatation, who were undergone catheterization and implanted the new-type occluder. 材料与方法:应用房间隔穿刺结合球囊扩张的方法建立ASD模型犬。
Conclusion The direction and the movement distance of experimental teeth were closely related with oral internal stress, transseptal fibers and resistance force; 结论牙齿移动的量、方向与颌骨内应力的分布、越隔纤维存在与否及牙齿移动方向上的阻力有无均有密切的关系;
The effect of cardioversion of atrial fibrillation ( Af) following percutaneous transseptal balloon mitral valvuloplasty was observed during 6 months of follow up in 20 patients with rheumatic heart disease for exploring the factors in cardioversion. 对二尖瓣球囊扩张成形术后心房颤动(Af)同步直流电复律20例患者的复律过程进行观察和随访,探讨复律的影响因素及窦性心律的维持。
