摘要:
目的:探讨在常规方法消融困难的左室特发性室性心动过速(ILVT)患者中室间隔左室面线性消融的有效性。方法: 18例术中不能诱发持续性心动过速或发作时不能耐受患者,进行室间隔左室面心尖到心底部连线的前1/3~1/2区域,在窦性心律下首先标到蒲肯野氏纤维电位(PP),向下至室间隔与左室下壁交界、向上至前后间隔中线进行线性消融,术后门诊或电话随访。结果: 所有患者术后即刻均未能诱发出ILVT。随访3~35(23±13)个月,3例/18例(17%)复发,远期成功率达83%,无1例发生永久性的并发症。结论: 对于术中不能诱发持续性心动过速或发作时不能耐受的ILVT患者,室间隔左室面线性消融安全有效,可以作为补救性消融措施。
Abstract:
AIM:To investigate the efficacy of linear ablation in the left ventricular (LV) septum in patients with idiopathic left ventricular tachycardia (ILVT) who were not amenable to “traditional” mapping. METHODS: In 18 ILVT patients, non-inducible/nonsustained VT and those unable to tolerate VT, a linear lesion along the mid to inferior septum was placed perpendicular to the long axis of the ventricle, approximately midway to one-third from the base to the apex in the region where the Purkinje potentials (PP) were recorded during sinus rhythm. RESULTS: During a follow-up of 22.8±12.6 months (range: 3-35 months), there were three recurrences of tachycardia in the 18 patients (16.7%). Long-term achievement ratio was 83.3% with no permanent complications. CONCLUSIONS: Linear ablation in the septum of the LV as a substitute mapping strategy was effective and safe in ILVT patients, noninducible/nonsustained VT and those unable to tolerate VT.
