[Atrial septal aneurysm. Report of two clinical cases and review of the literature]. / Aneurisma del setto interatriale. Descrizione di due casi clinici e revisione della letteratura.

We report two cases of atrial septal aneurysm, one associated with paroxysmal supraventricular tachycardia, the second with atrial septal defect. In both cases there were verified some transitory ischemic attacks. Carotid ultrasonography excluded atherosclerosis lesions. Two-dimensional transthoracic echocardiography showed an atrial septal aneurysm which, in the second case, was associated with atrial septal defect as demonstrated by color Doppler. The therapy is discussed in the case of septal atrial aneurysm associated with transitory ischemic attack, anticoagulant therapy is indicated; in the other, surgical correction of the defect is necessary.
