右侧0号Swartz鞘在升主动脉迂曲延长患者射频消融术中的新用途

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。

The experience of using R0 Swarts sheath in patients with tortuous and prolonged aorta

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.
