Core Tip

Core Tip: Bicuspid aortic valve (BAV) is a common congenital cardiac anomaly, frequently associated with aortopathy. Using third-generation dual-source computed tomography (CT) in 100 patients, we observed ascending aortic dilatation in 87% and identified a cohort-specific aortic size index threshold of 23.8 mm/m2 associated with CT-defined ascending aortic dilatation > 40 mm (sensitivity 84%, specificity 90%). Because aortic size index (ASI) is mathematically derived from the ascending aortic diameter, it is best interpreted as a cohort-specific threshold rather than as independent validation of ASI as a predictor. CT measurements were larger than transthoracic echocardiography (mean difference 11.72 mm), although this difference likely reflects differences in measurement sites, measurement conventions, and inherent limitations of 2D echocardiography in BAV rather than simple underestimation alone. These preliminary findings support further evaluation of indexed measurements alongside absolute diameter thresholds in populations with smaller body habitus, and will require validation in independent multicentre cohorts with longitudinal outcomes.
