Popis: Aortic root dilation (ARD) has been reported in patients with 22q11.2 deletion syndrome (22q11.2DS) with and without congenital heart defects (CHDs). However, the long-term implications of isolated ARD in 22q11.2DS remain undefined. In this study, we measured aortic root size and estimated the probability of changing between normal aortic root size and ARD during follow up to understand the prevalence, longitudinal course, and clinical risk factors for ARD in patients with 22q11.2DS without intracardiac CHDs. Aortic root size was measured in 251 patients with 432 studies. Forty-one patients (16.3%) had ARD on at least one echocardiogram and the cohort sinus Z-score was increased on the last echocardiogram [mean (1.09, SD 1.24) and median (1.20, min − 1.90 and max 5.40)]. Transition probability analysis showed that 8.1% of patients developed ARD and 45.4% of patients with ARD reverted to normal at the next echocardiogram. The risk of ARD over time was significantly associated with male sex (OR 3.06, 95% CI 1.41–6.65; p = 0.004), but not with age or presence of an aortic arch anomaly. Compared to a sinus Z-score ≥ 2, initial Z-score 4, and patients with initial Z-scores
