title: Is there a relationship between atrial septal aneurysm and atrial tachycardia?
abstract: We describe the case of a 37-year-old woman with atrial tachycardia associated to atrial septal aneurysm. We consider a localized reentry mechanism as the pathogenetic mechanism of the arrhythmia as demostrated by means of electrophisiological evaluation and electroanatomical mapping. The treatment by radiofrequency appears as an effective and well tolerated treatment of this unusual left atrial tachycardia.
