A. Measurement of the geometric height (gH) in a 2D plane bisecting the anterior and rightward truncal leaflet in diastole; B. Same measurement in volume rendered CT scan; C. Measurement of the geometric height (gH) in a 2D plane bisecting the anterior and rightward truncal leaflet in 3D echocardiogram (3DE) in diastole; D. Same measurement in volume rendering of 3DE; E. Segmented model of truncal valve in diastole; F. Segmented model of truncal valve in diastole with upper and lower annular rings demonstrating asymmetry of leaflet heights; F. Segmented model of truncal valve with upper and lower annular rings demonstrating asymmetry of leaflet heights. See Videos 2–4 for expanded description. Blue leaflet = Left anterior, Green leaflet = Right anterior, Yellow leaflet = Left posterior, Red leaflet = Right posterior.
