持续性心房颤动射频消融术中不同抗凝方案与围术期血栓事件的关系

Objective The relationships between different anticoagulation methods during radiofre-quency catheter ablation(RFCA) of persistent/permanent atrial fibrillation (AF)and thromboembolic events in our center were evaluated. Methods From July 2004 to October 2007, RFCA was consecutively performed in 145 persistent/permanent AF patients. Anticoagulation with warfarin was administrated in all patients before op-eration for at least 1 month, with the international normalized ratio(INR) maintained between 2.0 and 3.0. Be-fore procedure,warfarin was discontinued and replaced by low molecular weight heparin(LMWH). After atrial septum puncture,a total of 5000 U tmfractioned heparin(UFH) were given to patients of group Ⅰ who under-went the ablation from July 2004 to January 2006,while patients of group Ⅱ who underwent the ablation from February 2006 to October 2007 were heparinized(100 U/Kg) according to their weights. During operation, 1000 U UFH was appended per hour. After procedure, LMWH was used for 3 days while warfarin was initiated at the same time and continued for at least 3 months. Results Four patients in group Ⅰ (64 patients ,51 men)experi-enced thrombosis or embolism during or after ablation. One female persistent AF patient in the group Ⅱ (81 pa-tients,67 men)who didn' t fulfill the anticoagulatian therapy experienced TIA after ablation. No thrombeembolic event was identified in other patients of group Ⅱ who fulfilled the anticoagulation therapy. The incidence of thromboembolic event of persistent/permanent AF patients who fulfilled the anticoagulation therapy in the group Ⅱwas lower than that of group Ⅰ (4/64 vs. 0/80, P = 0.037). Conclusions Strengthen the anticoagulation therapy according to patients' weights during radiofrequency ablation could significantly decrease the incidence of thromboembolic event in patients with persistent/permanent AF.     

实时三维超声心动图定量评价扩张型心肌病患者心室内收缩同步性的研究

目的探讨实时三维超声心动图评价扩张型心肌病(DCM)患者左室内收缩同步性的临床应用价值。方法对32例DCM患者和31例正常志愿者应用超声技术获取左心室的全容积图像。计算左室17节段达到收缩期最小容积点的时间(Tmsv),并计算出左室16节段、12节段及6个基底段达到Tmsv的标准差和最大时间差(即Tmsv16-SD,Tmsv16-Dif,Tmsv12-SD,Tmsv12-Dif,Tmsv6-SD和Tmsv6-Dif)。结果DCM组的各项收缩不同步指标均显著高于正常组(均P<0.01)。与DCM伴左室收缩功能轻度减退组相比,DCM伴左室收缩功能中重度减退组的Tmsv16-SD、Tmsv12-SD、Tmsv16-Dif等指标均显著增高(均P<0.01)。所有受检者的全容积三维法测量的左室射血分数与二维Simpson法的测值呈高度正相关关系(r=0.912,P<0.001)。结论实时三维超声心动图及其定量分析软件能在同一心动周期内比较左室各节段的同步性,并提供血流动力学方面的信息,为临床评价左室内不同步提供了简便、直观、无创性的新方法。     

老年左房前壁自发性瘢痕相关心房扑动的电生理特征及分析

目的:探讨老年患者左房前壁自发性瘢痕相关心房扑动(房扑)的电生理特征及消融预后。方法:选择2018年1月至2020年1月复旦大学附属闵行医院收治的左房前壁自发性瘢痕相关的老年房扑患者5例,行电生理检查及三维电解剖指导下的射频消融术,平均年龄(76.6±10.5)岁,均为持续性房扑。术中通过激动标测、拖带标测以及电压标测等技术,确定房扑的诊断、机制、关键峡部及其与左房前壁自发瘢痕和低电压区的关系。结果:5例患者左房扩大,其中3例升主动脉内径增宽。5例患者均在左房前壁标测到低电压区和瘢痕区,多位于左房前壁靠近升主动脉压迹的部位。房扑均为折返性,关键峡部位于局部低电压区,消融后均成功终止房扑。其中1例因左房内径较大,同时行环肺静脉电隔离;1例复发,行二次消融。平均随访(15.6±4.2)个月后无复发。结论:左房前壁自发性瘢痕是部分老年患者左房房扑的发病基质,房扑的机制为折返性;左房内径扩大、升主动脉内径增宽可能与左房前壁瘢痕区和低电压区的形成相关。     

心房颤动射频消融术后心包积液的处理及危险因素分析

目的 探讨心房颤动(房颤)患者导管射频消融术后发生心包积液的处理并分析其相关危险因素.方法 156例房颤患者[男108例,女48例,阵发性房颤114例,平均年龄(57.6±11.3)岁]在三维标测系统及环状标测电极导管指导下行射频消融治疗[包括环肺静脉电隔离、线性消融及(或)碎裂电位消融],记录消融过程、部位、时间等因素,对术后证实出现心包积液的患者根据不同情况(心脏压塞或单纯心包积液)进行不同处理,并门诊随访心脏超声等.对可能影响术后出现单纯心包积液的因素进行分析.结果 所有156例患者均完成肺静脉电隔离,共有16例(10.3%)出现心包积液,其中1例(0.6%)术后即刻出现心脏压塞,予心包穿刺后开胸探查抢救好转,随访18个月无特殊;另15例(9.6%)术后出现少量心包积液但无心脏压塞表现(单纯心包积液组),经保守治疗后好转,其中6例患者的心包积液在术后3个月消失,而另外9例则在术后6个月消失.单因素分析发现,单纯心包积液组与无心包积液组在性别组成(P<0.01)、有无行冠状静脉窦消融(P=0.026)、有无行碎裂电位消融(P=0.037)、有无行上腔静脉消融(P=0.041)等方面差异有统计学意义.Logistic多因素回归分析发现,女性[B=3.594,exp(b)=36.4,95%CI:4.2-312.1,P=0.001]、行冠状静脉窦消融[B=2.419,exp(b)=11.2,95%CI:1.0～124.6,P=0.049]是术后出现单纯心包积液的独立危险因素.结论 房颤射频消融术后心包积液的发生率较高,但绝大部分并不出现心脏压塞,可经保守治疗得到改善,而不需要进一步有创治疗.女性及行冠状静脉窦消融是术后出现单纯心包积液的独立危险因素,房颤射频消融时应谨慎对待该部位的消融,以减少术后心包积液的发生.
