【摘要】 目的　总结右侧 0号Swartz鞘在升主动脉迂曲延长患者射频消融术中应用的体会。方法　对 4例升主动脉迂曲延长的患者 (其中 3例左侧旁道、1例左室特发性室性心动过速 ) ,在消融导管无法进入升主动脉或左心室时 ,选用右侧 0号Swartz鞘 ,利用其头端较小的弯度 ,使消融导管顺利地经升主动脉进入左心室。结果　 4例升主动脉迂曲延长的患者经上述方法消融成功。结论　对升主动脉迂曲延长患者 ,如果没有条件进行房间隔穿刺 ,可以使用右侧 0号Swartz鞘协助导管操作 ,有助于缩短手术时间、避免并发症。更多还原

【Abstract】 Objective To report the experience of using R 0 Swartz sheath in patients with tortuous and prolonged aorta. Methods The radiofrequency ablation procedure could not be done in 4 patients (3 patients with left side accessory pathway, and 1 with idiopathic left ventricular tachycardia) because the ablation catheter could not be put in left ventricle due to tortuous and prolonged aorta. We tried to use R 0 Swartz sheath in these patients in order to put the catheter into left ventricle via small curve of the R 0 Swartz.Results The ablation procedures were successful in these 4 patients by using R 0 Swartz.Conclusion Using R 0 Swartz sheath in patients with tortuous and prolonged aorta is helpful in making the left side ablation procedure successful.更多还原
