2.5 Variables analyzed
The following information was obtained from patients’ records and compared between the 2 study groups: patients’ clinical characteristics at the time of the procedure, e.g., age, sex, presence of diabetes mellitus, CHADS2 and CHA2DS2-VASc scores, creatinine and NT-proBNP concentrations, and echocardiographic variables plus patients’ CT-based measured wall thicknesses and variables related to the ablation procedure. Also compared was the modified AI for segments with a gap in the ablation line vs. that for segments without a gap in the ablation line.
