患者男,42岁。因二尖瓣脱垂伴二尖瓣、三尖瓣关闭不全、持续性心房颤动(简称房颤)行外科二、三尖瓣成形术及房颤射频消融术。术后发生持续性房性心动过速(简称房速),伴阵发性房颤。再次入院行经皮穿刺心内电生理检查发现左上肺静脉电位延迟,其余肺静脉电位均未延迟或消失,并根据三维电解剖激动标测结果消融中止房速,再次隔离肺静脉。结论:尽管外科房颤射频消融相对直观,但获得完全性永久的线性损伤亦非易事。
Male patient, 42 years old. Due to mitral valve prolapse with mitral, tricuspid regurgitation, persistent atrial fibrillation (referred to as atrial fibrillation) surgery two tricuspid valvuloplasty and atrial fibrillation radiofrequency ablation. Postoperative persistent atrial tachycardia (referred to as atrial tachycardia), with paroxysmal atrial fibrillation. Again admission percutaneous cardiac electrophysiological examination found that the left upper left ventricular electrical potential delay, the rest of the pulmonary venous potential were not delayed or disappeared, and according to the results of three-dimensional electroanatomic excitement ablation termination of atrial tachycardia, pulmonary vein isolation again. CONCLUSIONS: Although radiofrequency ablation of the surgical AF is relatively straightforward, obtaining a completely permanent linear lesion is not easy.
