title: [Ectopic atrial tachycardia complicating a congenital left atrial aneurysm: value of an electro-anatomical mapping system].
abstract: The authors report the case of a patient with a congenital left atrial aneurysm complicated by ectopic atrial tachycardia treated successfully by surgery. Transoesophageal echocardiography and magnetic resonance imaging provided accurate measurements of the aneurysm and its anatomical relationships. Three-dimensional electro-anatomical mapping with the CARTO, system (Biosense) confirmed the shape and dimensions of the aneurysm. The system showed the electrically mute zones and the ectopic focus situated just beyond the aneurysmal neck. Surgical ablation confirmed the morphological and functional data of the imaging techniques and the patient was definitely cured.
