摘　　要：目的探讨使用冷冻直导管节段消融肺静脉治疗心房颤动（房颤）的可行性和短期治疗效果。方法选择临床确诊阵发性房颤患者11例，采用6mm冷冻直导管、Lasso导管标测肺静脉电位，节段消融电隔离肺静脉，肺静脉电位消失30min为消融隔离成功。结果平均消融术时间（252．55±51．99）min，曝光时间（35．65±9．88）min。共隔离36根肺静脉，平均每根静脉冷冻（7．9±4．1）次。消融即刻成功率100％。平均随访（8．73±4．15）个月，短期成功率81．8％。结论冷冻直导管节段消融肺静脉治疗房颤的短期效果较好。Objective To investigate the short-term effect of transvenous catheter pulmonary vein seg- mental cryoisolation. Methods Eleven patients with paroxysmal atrial fibrillation, underwent pulmonary vein segmental cryoisolation using a 6mm cryo-eatheter. Results A total of 36 pulmonary veins were isolated by ablating for （7.9± 4.1） times. Procedual time was （252. 55±51.99） min, and X-ray explosion time was （35.65±9.88）min. During follow-up of（8.73±4. 15） months, the clinical efficacy rate was 81.8%. Conclusion Transvenous catheter pulmonary vein segmental cryoisolation for treatment of atrial fibrillation is effective.
