Key result
SafeSept J-shaped guidewire enables successful completion of difficult trans-septal puncture during AF ablation.
Why the study?
Access to the left atrium via trans-septal puncture can be difficult despite normal septal anatomy and conventional guidance techniques.
Case Report (n=1)
No
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.

Zucchetti et al. (2015) conducted a case report in Paroxysmal atrial fibrillation refractory to antiarrhythmic drug therapy (n=1). SafeSept trans-septal guidewire was evaluated on Successful trans-septal puncture. A difficult trans-septal puncture during catheter ablation for atrial fibrillation was successfully carried out using a novel nitinol J-shaped SafeSept trans-septal guidewire.
