【摘要】 目的 探讨心腔内超声（intracardiac echocardiography,ICE）对“潜在型”卵圆孔未闭（patent foramen ovale,PFO）介入封堵术的应用价值。方法 回顾性研究复旦大学附属中山医院2021年6—9月收治的术前右心声学造影显示Valsalva动作后出现房水平分流的PFO患者并行介入手术者，根据术中是否运用ICE分为经胸心超（transthoracic echocardiography,TTE）组与ICE组，记录两组的一般情况、超声结果、合并症、并发症、手术时间以及透视时间等临床资料。Pearson法分析术中ICE下测量的卵圆孔直径与术前经食管超声心动图（transesophageal echocardiography,TEE）测量直径的相关性。结果 纳入56例患者，其中TTE组37例，ICE组19例。术中ICE下测量的卵圆孔直径与术前TEE下测量的直径呈正相关（R=0.81,P<0.01），术中可以指引导丝通过卵圆孔，减少手术时间和射线照射时间。结论 ICE对“潜在型”PFO介入封堵术有显著的应用价值，和TTE相比有更高的成功率和安全性，能减少手术时间和射线照射时间。更多还原

【Abstract】 Objective To investigate the application value of intracardiac echocardiography(ICE) in transcatheter closure of latent patent foramen ovale(PFO). Methods This was a retrospective study of patients admitted to Zhongshan Hospital,Fudan University from Jun to Sep 2021 who showed atrium level shunt after valsalva maneuver by right heart contrast echocardiography and received transcatheter closure.They were divided into transthoracic echocardiography(TTE) group and ICE group according to using ICE or not. The general condition, ultrasound results, comorbidity, complications, operative and fluoroscopy time of two group were recored. Pearson correlation was used to analyze the correlation between diameter of foramen ovale measured by ICE during the operative and transesophageal echocardiography(TEE) before. Results Among 56 patients, there were 37 patients in TTE group and 19 patients in ICE group. Correlation analysis showed that the diameter of foramen ovale measured by ICE was positively associated with TEE(R=0.81,P<0.01). ICE could guide wire to pass through the foramen ovale during operation, which reduced the operation time and radiation exposure time. Conclusion ICE had significant value in transcatheter closure of latent PFO. It has not only a higher successful rate and safety, but also reduce the operation time and radiation exposure time compared to TTE.更多还原
