摘要
目的:探讨消融疼痛对肺静脉隔离时导管贴靠压力(CF)的影响。方法:连续入选2023年2月至5月因药物难治性心房颤动到阜外华中心血管病医院就诊并行射频导管消融治疗的患者40例。将两侧肺静脉各分为8个区域。记录导管与心房组织的CF和贴靠稳定(至少50%导管贴靠时间CF≥10 g)的消融点数量。根据面部疼痛量表(修订版)对患者进行疼痛评估,每个消融区域取最大疼痛值。根据疼痛评分高低,将各区域疼痛评分较高的20例分为疼痛组,较低的20例分为普通组。分析各部位CF特征和与疼痛之间的关系。结果:在40例心房颤动患者中共记录3832个环肺静脉消融点,CF为(12.2±7.8)g。疼痛组的CF显著低于普通组[(11.1±5.1)g vs.(13.4±4.8)g,P<0.05]。右上肺静脉顶部是CF最大的区域,为(16.5±5.8)g,左侧前壁上部(左心耳嵴部)是CF最小的区域,为(7.5±3.7)g。在右下肺静脉底部、右侧后壁下部、左下肺静脉底部、左侧后壁下部、左侧后壁中部、左侧后壁上部区域,疼痛组的CF均显著小于普通组(P均<0.05)。在3832个消融点中,贴靠稳定的消融点有2193个(57.2%),疼痛组贴靠稳定的消融点构成比显著低于普通组(55.2%vs.59.5%,P<0.05)。在右下肺静脉底部、右侧后壁下部、左侧前壁下部、左下肺静脉底部、左侧后壁中部、左侧后壁下部区域,疼痛组贴靠稳定的消融点构成比均低于普通组(P均<0.05)。此外,左肺静脉贴靠稳定消融点的构成比更低(54.2%vs.60.5%,P<0.05),尤其是在左侧前壁上部(左心耳嵴部),40例患者224个消融点中,仅有88个(39.3%)贴靠稳定的消融点。结论:消融时疼痛会影响导管与心房组织的贴靠稳定,术者应实时监测CF,以提高肺静脉隔离效果,尤其是在疼痛更剧烈的部位。
Objectives:The present study evaluated the impact of ablation pain during pulmonary vein isolation(PVI)on cathetertissue contact at different regions.Methods:Forty consecutive patients with atrial fibrillation(AF)referred to Central China Fuwai Hospital for catheter radiofrequency ablation from February to May 2023 were enrolled.The pulmonary veins on each side were divided into 8 regions.The catheter-tissue contact force(CF)and the number of ablation contact stability(>50%catheter attach time CF≥10 g)of each ablation lesion were analyzed.Pain scores during the ablation were assessed using the Faces Pain Scale-Revised and the maximum score was taken for each ablation region.Based on the pain scores,in each region,20 cases with higher pain scores were categorized into the pain group and 20 cases with lower pain scores were categorized into the normal group.The CF characteristics of each region and the relationship with ablation induced pain were analyzed.Results:A total of 3832 lesions were recorded in 40 patients with AF,with a mean CF of(12.2±7.8)g.Among them,the CF in the pain group was significantly lower than that in the normal group([11.1±5.1]g vs.[13.4±4.8]g,P<0.05).The top region of the right pulmonary vein was the region with the largest CF(16.5±5.8)g,and the upper part of the left anterior wall(at the ridge between the left atrial appendage)was the region with the smallest CF(7.5±3.7)g.At the bottom of right pulmonary vein,right lower posterior wall,left pulmonary vein,and left posterior wall,as well as the middle region of left posterior wall,and upper region of left posterior wall,the CF was significantly smaller in the pain group than that in the normal group(all P<0.05).Of the 3832 lesions,2193(57.2%)were stable lesions,and the proportion of stable lesions in the pain group was significantly lower than that in the normal group(55.2%vs.59.5%,P<0.05).In the right pulmonary vein bottom,right lower posterior wall,left lower anterior wall,left pulmonary vein bottom,and left lower posterior wall,the
