1 Introduction In the 70's,we classified for the first time the blocks at the atrial level into interatrial blocks（IAB）,[1]partial and advanced,and other types of atrial blocks including the concept of atrial aberrancy,and atrial dissociation.[2]The concept of IAB,the most frequent and relevant blocks at the atrial level mean that exist a delayed conduction between the right and left atrium（RA and LA）.We also divided them using the same concept as at ventricular,sinoatrial,

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 "Safe Sept" 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 "Safe Sept" guidewire, when advanced into the left atrium, becomes atraumatic.

1 Risk of stroke in patients with high CHA2DS2VASc and no documented arrhythmias Recent studies have suggested that patients with high CHA2DS2VASc-score[Congestive Heart failure,hypertension,Age≥75 years（doubled）,Diabetes,Stroke（doubled）,Vascular disease,Age 65-74 years,Sex category（female sex）]thromboembolic complications occurred irrespective of the presence of atrial fibrillation（AF）and anticoagulant therapy may be initiated irrespective of documented AF.[1,2]
