Résumé
Catheter ablation of arrhythmogenic triggers has been validated for the treatment of atrial fibrillation that is refractory to anti-arrhythmic medication. Imaging plays an important role in guiding the procedure as well as in planning and follow-up. The goal of pre-procedural imaging is to obtain a detailed anatomical description of the pulmonary veins, to eliminate a thrombus of the left atrium and to define the prognostic factors. MDCT angiography effectively and simply meets nearly all of these needs. Thus, a precise description of the left atrium anatomy before the procedure is a key factor to success and left atrium volume is a reliable prognostic factor of recurrence. Radiologists should be aware of early and late complications, sometimes severe such as pulmonary vein stenosis, cardiac tamponade or atrial-esophageal fistula, whose positive diagnosis is based on imaging.
