Comparison of computed tomography of the left atrium with and without ECG gating before atrial fibrillation catheter ablation - a prospective, randomized, double-blind study

Popis výsledku v původním jazyce

Background: A fusion of electroanatomical (EA) map with a 3D computed tomography (CT) model of left atrium (LA) is routinely used to acquire anatomical details before atrial fibrillation (AF) catheter ablation (CA). A widely-used gold standard for a CT procedure is not defined. Methods: 62 patients scheduled for AF ablation were randomized 1:1 for two types of LA CT. Group 1: CT with retrospective ECG gating. Group 2: helical CT without ECG gating. A visual 5-point scale was used for CT image quality assessment. CT Dose Index (CTDIvol) and Dose Length Product (DLP) were used to compare radiation exposure. CA was done by a CT-type-blinded operator. A fast EA map (FAM, CARTO3) and merge with LA model (Carto3-Merge) were used. Variance between EA map and CT model were evaluated automatically by CARTO3 software. Results: We have found a significant difference between both groups in radiation dose – CTDI (89.55±5.99 vs. 19.19±4.33 mGy, p<0.0001), DLP (1438.87±147.75 vs. 328.21±73.83 mGy$·$cm, p<0.0001). There was no difference between the groups in visual data quality (1.77±0.88 vs. 2.0±0.63, p=0.102), average CT/FAM variance (2.42±0.72 vs. 2.43±0.46 mm, p=0.612), CA length (131.61±32.57 vs. 119.84±33.18 min, p=0.108), CA fluoroscopy time (4.48±2.19 vs. 3.89±1.83, p=0.251) and CA fluoroscopy length (4258.26±2964.94 vs. 4075.68±2845.85, p=0.741). There was no difference in body-mass-index (27.92±4.46 vs. 29.66±3.51, p=0.116). The study was stopped prematurely by a Safety Monitoring Board based on these results.
