Popis: International audience; INTRODUCTION: The distance from the descending aorta (DA) to the posterior wall of the left atrium (LA) is variable. We aimed to determine whether the proximity between the DA and the left inferior pulmonary vein (LIPV) ostium has an impact on biophysical parameters and cryoballoon (CB) ablation efficacy during LIPV freezing. METHODS: Patients referred for CB-ablation of atrial fibrillation (AF) in two high-volume centers were included. Cryoablation data were collected prospectively for each patient. The anatomical relationships between the LIPV and the DA (distance LIPV ostium-DA, presence of an aortic imprint on the posterior aspect of the LIPV) were then retrospectively analysed on the LA computed tomography (CT) scans realized before AF ablation. RESULTS: 350 patients were included (70% men, 59.7±11.5 yo). The decrease in the Ostium-DA distance was significantly correlated to the increase in the Time-To-Isolation (TTI) (r=-0.31; p=0.036), with less negative temperature (r=-0.11; p=0.045). Similarly, the presence of an aortic imprint on the LIPV was associated with a longer TTI (p
