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。

Methods: a new self - manufactured LAA occluder was implanted into the LAA through a transseptal catheter in 20 dogs.

方法：用自行研制的新型左心耳封堵器经导管封堵20只犬的左心耳。

The puncture device is adjustable from a position within the dilator to a position extending beyond the end of the dilator when necessary for use in transseptal procedures.

当 经中隔过程中要用到时，穿刺装置可从扩张器中的位置调整到延伸超出扩 张器的端部的位置。
