目的

探讨三维标测系统结合心腔内超声(ICE)技术指导心房颤动(房颤)零射线导管射频消融的可行性与安全性。

方法

本研究为病例对照研究,连续纳入2024年5月至2024年11月在苏州大学附属第一医院心内科拟行射频消融的房颤患者。所有患者均采用三维标测系统和ICE,根据术中射线使用情况分为零射线组和低射线组。比较两组间患者年龄、左心房前后径等临床基线资料,房间隔穿刺时间、肺静脉隔离时间等手术步骤时间,X线曝光时间、剂量等术中X线使用情况及心房食管瘘、心脏压塞等围手术期并发症发生率的差异。

结果

纳入92例患者,年龄68.5(58.0,73.0)岁,男占70.0%(57/92)。其中零射线组75例,低射线组17例。零射线组患者年龄较低射线组小[67.0(57.0,72.0)岁对75.0(60.5,78.0)岁,P=0.014],两组患者性别、左心房前后径等临床基线资料差异无统计学意义(P>0.05)。与低射线组相比,零射线组患者总手术时间较短[120.0(109.0,131.0)min 对135.0(120.0,184.5)min,P=0.019]、X线曝光时间短[0(0,0)min对2.0(1.0,5.5)min,P<0.001]、X线曝光量低[0(0,0)mGy对34.0(4.5,46.5)mGy,P<0.001]。多重线性回归分析显示,在校正了年龄后,零射线组与较低的手术时间、X线曝光时间及较少的X线曝光量相关。两组患者围手术期均未发生严重并发症。

结论

三维标测系统结合ICE指导零射线房颤射频导管消融安全、可行。

Objective

To evaluate the feasibility and safety of zero-fluoroscopy radiofrequency catheter ablation guided by the 3D mapping system and intracardiac echocardiography (ICE) compared with traditional fluoroscopy-assisted radiofrequency catheter ablation for the treatment of atrial fibrillation.

Methods

This case-control study continuously enrolled patients with atrial fibrillation who underwent radiofrequency ablation at the Department of Cardiology, The First Affiliated Hospital of Soochow University from May 2024 to November 2024. All procedures utilized a 3D mapping system and ICE. Participants were divided into the zero-fluoroscopy group and the low-fluoroscopy group based on intraoperative fluoroscopy usage. Clinical baseline characteristics including age and left atrial anteroposterior diameter, time of each procedure such as time for transseptal puncture and pulmonary vein isolation, intraoperative radiation exposure parameters including fluoroscopy time and radiation dose, and incidence of perioperative complications such as atrioesophageal fistula and cardiac tamponade were compared between the two groups.

Results

This study enrolled a total of 92 cases [70.0% (75/92) males, median age 68.5 (58.0, 73.0) years], with 75 in the zero-fluoroscopy group and 17 in the low-fluoroscopy group. The zero-fluoroscopy group exhibited a younger age compared to the low-fluoroscopy group [67.0 (57.0, 72.0)] years vs. 75.0 (60.5, 78.0) years, P = 0.014], while no statistically significant difference was observed in other baseline clinical characteristics such as age and left atrial anteroposterior diameter(P > 0.05). Compared to the low-fluoroscopy group, the zero-fluoroscopy group demonstrated shorter total procedure time [120.0 (109.0, 131.0) min vs. 135.0 (120.0, 184.5) min, P = 0.019], reduced X-ray exposure duration [0 (0, 0) min vs. 2.0 (1.0, 5.5) min, P < 0.001], and lower X-ray radiation dose [0 (0, 0) mGy vs. 34.0 (4.5, 46.5) mGy, P < 0.001]. Multivariate linear regression analysis demonstrated that the zero-fluoroscopy group was significantly associated with shorter procedure time, reduced fluoroscopy time, and lower radiation dose with adjustment for age as a confounder. No severe perioperative complications occurred in either group.

Conclusion

Zero-fluoroscopy radiofrequency catheter ablation for atrial fibrillation, guided by a 3D mapping system combined with ICE, is safe and feasible.
