食管造影及温度监测指导环肺静脉消融治疗心房颤动

Objective Because of the severe consequences of an atrial esophageal fistula,it is vital to avoid this complication. The most safe way is to avoid ablating the segment of esophagus behind left atrium (LA). What we do is to image the relationship of esophagus to posterior LA wall and real-time esophageal tem-perature monitoring to ablate the posterior LA wall. Methods Sixty-four patients with paroxysmal atrial fibrilla-tion (PAF) were enrolled to pulmonary veins (PV) isolation. Swallowing a radiocontrast agent at the same time when imaging of LA to observe the relationship of esophagus to posterior LA wall and according to the different relationship between the segment of esophagus behind LA and PV, the esophagus were divided into type Ⅰ , type Ⅱ and type Ⅲ. A esophageal temperature probe was inserted and advanced into the esophagus directly posterior to the LA. Three steps ablation strategy and real-time esophageal temperature monitoring were applied to guide the PV isolation. The procedure was interrupted when the esophageal temperature was 39℃ until] the tempera-ture renormalized and ended when PV were isolated. Results There were 48 type ⅠI , 11 type Ⅱ and 5 type Ⅲ esophagus in the 64 patients. After three steps ablation,all PV isolations were completed. Only 18.8% of the patients needed to ablate the posterior LA close to the esophagus. Conclusion Only one PV ostiolum close to the posterior LA wall in most PAF patients and many of them can achieve complete PV isolation without ablating the posterior LA close to esophagus which could minimize the risk of esophageal injury dramatically.

冠状动脉介入术患者的意识镇静及其对血流动力学的影响

Objective To observe the safety of midazolam and fentanyl in coronary intervention and its effect on haemodynamics. Methods 150 cases undergoing coronary intervention were randomly divided into three groups(n=50 for each):the control group were given injection of 5 ml saline,midazolam group were given 0.04 mg/kg midazolam and combined fentanyl group were given injection of 0.02 mg/kg midazolam with 1.2μg/kg fent-anyl intravenously. Heart rate(HR),mean blood pressure(MAP),SpO<,2>,OAA/S and BIS were observed during the intervention and the patients' satisfaction and the incidence of complications were investigated. Results There was no significant difference among the three groups in MAP and HR (F=3.34,2.98,P>0.05). MAP increased from (95.7±14.5) mm Hg to (85.4±15.3) mm Hg after treatment (t=4.34,P<0.01) and HR increased from (83.3±23.4) times/min to (78.4±22.7) times/min in control group (t=3.37,P<0.01). BIS score was (90.5±7.2),(75.5±12.8) and (72.3±14.1) during intervention and 24 hVAS score was (53.5±25.4),(58.8±18.2) and (71.9±16.8) in control group,midazolam group and combined fentanyl group,with significant difference between groups (F=10.89,8.56,P<0.01). Conclusion Low dose of midazolam and fentanyl can make the patients calm,which relieves the tensity and anxiety and enhance the tolerance and safety of intervention but has no remarkable effect on bemodynamics.     

踝臂指数与冠状动脉病变严重程度的相关性研究

目的评价踝臂指数(ABI)与冠状动脉病变严重程度的相关性。方法选择162例冠状动脉造影术或介入治疗的患者,采用全自动动脉硬化测定仪测定ABI,重点观察ABI与冠状动脉病变Gensini评分的相关性及对严重冠状动脉病变的预测价值。结果冠心病组与非冠心病组相比较ABI差异具有统计学意义(0.97±0.22 vs 1.09±0.11,P<0.001),比较无病变组、轻度病变组、严重病变组的SBP[(137±17),(147±17)和(159±21)]、PP[(57±12),(67±12)和(81±17)]、HDL-C[(1.28±0.21),(1.22±0.31)和(1.14±0.33)]、ABI值[(1.12±0.16),(1.01±0.18)和(0.85±0.21)],差异有统计学意义(P<0.05),观察SBP、PP值,严重病变组高于轻度病变组(P<0.05),轻度病变组高于无病变组(P<0.05)。观察ABI值则是无病变组高于轻度病变组(P<0.05),轻度病变组高于严重病变组(P<0.05)。冠状动脉入选患者的Gensini评分与ABI呈显著负相关(r=-0.522,P<0.001)。多变量logistic回归分析显示糖尿病史、HDL-C、SBP、ABI≤0.9是严重冠状动脉病变的预测因子。结论踝臂指数与冠状动脉病变程度关系密切,有助于预测冠状动脉病变严重程度。     

单纯环肺静脉前庭隔离术治疗持续性心房颤动:单中心三年随访结果

Objective To report the long-term outcome of catheter radiofrequency ablation treatment for patients with persistent atrial fibrillation (PerAF) and discuss the impact of PerAF duration and the termi-nation on the therapeutic outcome. Methods Eight-six consecutive PerAF patients underwent circumferential pulmonary vein antrum isolation (CPVAI) only were included in this study. Based on PerAF duration, patients were divided into two groups: short term (≤1 year, n =47) and long term (> 1 year, n =39). Results The mean follow-up period was 25-50 (36 ± 8) months. During the follow-up period, the success rate after single procedure was 30. 2% (26/86). Late recurrence phenomenon, defined as atrial tachyarrhythmias relapsed 1 year later, was observed in 9 patients (10.5%). The long-term success rate in the short term group was signifi-cantly higher than that in long term group (42.5% vs 15.4% ,P <0.01). During the first procedure, atrial fi-brillation converted into sinus rhythm or atrial tachycardia occurred in 29 patients (33.7%). Compared with the another 57 patients, the long-term outcome of these patients was much better (48.3% vs 21.1% ,P < 0.01). Redo procedures were pedormed in 24 patients (27.9%), which increased the total success rate at 3 years follow-up to 41.9% (36/86). Conclusion The long-term outcome treated with CPVAI in patients with PerAF is still unsatisfactory. In addition, the late recurrence is common. Shorter term of PerAF and terminated by ablation indicate that those patients might get more benefit from the CPVA1 treatment.
