Data are reported as the mean ± standard deviation for normally distributed and as the median (25th, 75th percentiles) for nonnormally distributed variables. DL, deep-learning; BAV, bicuspid aortic valve; LVOT, left ventricular outflow tract; D, diameter; pDD, perimeter-derived diameter; aDD, area-derived diameter; STJ, sinotubular junction; AAo, ascending aorta.
