A 69-year-old man was admitted to our center to undergo catheter ablation of paroxysmal atrial fibrillation refractory to antiarrhythmic drug therapy. This procedure required access to the left atrium through the interatrial septum. During hospitalization, the patient performed routinely pre-procedure transthoracic echocardiography and gadolinium-enhanced cardiac magnetic resonance showing a normal anatomy of both the fossa ovalis and the interatrial septum. Access to the left atrium proved difficult and several unsuccessful attempts to perform the trans-septal puncture were made under both fluoroscopy and intracardiac echocardiography guidance, even with radiofrequency energy delivery. Finally, trans-septal puncture was successfully carried out using a novel nitinol J-shaped "SafeSept" trans-septal guidewire, designed to cross the interatrial septum through the trans-septal needle thanks to a special sharp tip. Moreover, thanks to its rounded J shape that reduces the risk of atrial perforation, the "SafeSept" guidewire, when advanced into the left atrium, becomes atraumatic.
一名69岁男性因抗心律失常药物治疗无效的阵发性心房颤动入住我院接受导管消融治疗。该手术需要通过房间隔进入左心房。住院期间，患者常规进行了术前经胸超声心动图和钆增强心脏磁共振检查，结果显示卵圆窝和房间隔的解剖结构正常。结果发现进入左心房困难，在荧光透视和心腔内超声心动图引导下，甚至使用射频能量传递，进行了几次经间隔穿刺均未成功。最后，使用一种新型镍钛合金J形“SafeSept”经间隔导丝成功完成了经间隔穿刺，该导丝设计有特殊尖锐尖端，可通过经间隔穿刺针穿过房间隔。此外，由于其圆形J形可降低心房穿孔风险，“SafeSept”导丝进入左心房时不会造成创伤。
