摘要

背景：在经皮左心耳闭塞术（LAAO）中，虽然提出了自动校准或基于导管直径校准的方法进行透视测量，但这种方法可能不精确，导致测量错误。我们试图研究在透视下使用表面钢球校准（SSBC）方法是否可以促进LAAO植入后WATCHMAN装置（Boston Scientific Corporation, Natick， MA， USA）的透视测量。方法：本回顾性研究包括97例使用WATCHMAN装置经皮LAAO的患者。LAAO过程中采用SSBC法、透视下鞘鞘校准法和经食管超声心动图（TEE）测量植入后装置的直径。然后比较了三种方法的结果。结果：WATCHMAN手术植入成功率为100% %。post-implanted设备的平均最大直径是24.7 ±  3.1毫米,23.5 ±3.2  毫米,和24.2 ±3.0  毫米,以SSBC方法,鞘校准方法,分别和三通(所有p 结论:SSBC方法,当采用透视下,表现出高度的相关性与鞘校准方法和t形测量。它可以应用于经皮LAAO过程中方便的透视测量。

Surface steel ball calibration — A novel method for facilitating fluoroscopic measurement during implantation of WATCHMAN

Background

Although the method of autocalibration or calibration based on catheter diameters was proposed for fluoroscopic measurement during percutaneous left atrial appendage occlusion (LAAO), it may be imprecise and lead to mismeasurement. We sought to investigate whether the utilization of the surface steel ball calibration (SSBC) method under fluoroscopy could facilitate the fluoroscopic measurement of the post-implanted WATCHMAN device (Boston Scientific Corporation, Natick, MA, USA) in LAAO.

Methods

This retrospective study included 97 consecutive patients who underwent percutaneous LAAO with the WATCHMAN device. The SSBC method and sheath calibration method under fluoroscopy, and transesophageal echocardiography (TEE) were employed to measure the diameter of the post-implanted device during the LAAO procedure. The results of the three methods were then compared.

Results

The success rate for procedural WATCHMAN implantation was 100 %. The mean maximal diameter of the post-implanted devices was 24.7 ± 3.1 mm, 23.5 ± 3.2 mm, and 24.2 ± 3.0 mm, as measured by the SSBC method, sheath calibration method, and TEE, respectively (all p < 0.001). The relevant coefficient of correlation between the SSBC method/TEE, SSBC method/sheath calibration method, and TEE/sheath calibration method, was 0.94, 0.93, and 0.89, respectively (all p < 0.001).

Conclusion

The SSBC method, when employed under fluoroscopy, demonstrated a high correlation with the sheath calibration method and TEE for measurements. It may be applied to facilitate fluoroscopic measurements during percutaneous LAAO procedures.
