无左心房和肺静脉三维重建的阵发性心房颤动导管消融术

Objective To investigate the differences between modeling and non-modeling left atrium in Carto XP system guided catheter ablation for paroxysmal atrial fibrillation. Methods Thirty-one cases of par-oxysmal atrial fibrillation treated by the same electrophysiologist with guidance of Carto XP during Jan to Dec in 2008 were enrolled. Catheter ablation was accomplished without left atrium and pulmonary veins modeling in 17 patients (non-modeling group) and with left atrium modeling in 14 patients (modeling group). The detailed ablation method was based on circumferential pulmonary veins isolation (CPVI). And linear ablation of tricus-pid valvular isthmus was selectively proceeded individually. The ablation endpoint was set to complete isolation of pulmonary vein potential from left atrium and no continuous fast atrial arrhythmia including atrial fibrillation, atrial flutter and atrial tachycardia could be induced. Comparisons for each step during procedure and the fol-low-up outcomes had been done. Results The male: female ratio of the 2 groups were 10:4 and 11 : 6 (P >0.05). The average age were (54.64 ± 15.58) and (59.41 ± 10.59) (P >0.05) ,the diseased courses were (5.05 ±10.4) years and (7.34±7.74)years(P >0.05),the left atrial sizes were (35.29±4.73) mm and (36.47 ±6.15)mm (P > 0.05), the total procedure time was (107.23±28.92) rain and (93.47 ±26.09) win (P>0.05). The X-ray exposure time was (21.09 ±6.49)min (modeling group) and (14.16±5.35)min (non-modeling group,P < 0.05). The CPVI time of fight pulmonary veins was (27.29±18.53) rain (model-ing group) and 18.00 ±4.51 min (non-modeling group, P < 0.05). The CPVI time of left pulmonary veins was (28.14 ±9.26) rain (modeling group) and (23.94±7.10) rain (non-modeling group, P < 0.05). The successful rates was 85.7% (modeling group) and 82.4% (non-modeling group, P > 0.05) over follow-up for 2 to 13 months. Conclusion Carto system guided catheter ablation of paroxysmal atrial fibrillation without modeling of left atrium and pulmonary veins could take less time in X-ray exposure and ablation steps, compa-ring with left atrium modeling one.     

右室特发性室性心动过速的射频消融

目的 报道5例右室间隔特发性室性心动过速的电生理标测及射频消融治疗。方法 用7FEPT温控大头电极导管进行消融,心动过速时在右室后间隔标侧到明显提前的P电位处为消融靶点,以温控50～55℃、功率30～35W放电。3s心动过速终止,巩固放电40s,然后行常规心内电生理检查,不能诱发心动过速作为消融终点。术后口服Aspirin 0.1g/d 1个月。结果 放电消融5s内心动过速终止,巩固放电40s,消融前后体表心电图无明显改变。术后心室S1S2程序刺激,静脉滴注异丙肾上腺素后,重复上述刺激,均不能诱发心动过速,射频消融成功。随访4～22个月,无心动过速发作,无并发症出现。结论 (1)在右室后间隔也能形成类似于左室后间隔的特发性室性心动过速,在标测到明显提前的P电位处消融容易获得成功。(2)右室特发性室性心动过速在心动过速时也有典型的体表心电图特征。(3)此型室性心动过速应与束支折返性室性心动过速相鉴别。
