24 patients with various forms of endocardial cushion defect, ranging in age from 8 months to 22 years, were studied by single crystal (M mode) and two-dimensional (2 D) echocardiography. In all of them diagnosis was confirmed by cardiac catheterization and angiocardiography, in 8 of them at surgery and in 3 of them at autopsy. From the morphologic point of view, 2 D echocardiography appeared to integrate M mode recording in the structural definition of atrioventricular valves and in a better differentiation of complete atrioventricular canal. M mode scanning right atrium-left ventricle, transverse projection by multiscan and long-axis and apical projections by sector-scanner were the most diagnostic projections. From the functional point of view, in patients with complete right bundle branch block (QRS > 120 msec), right ventricular isovulumetric contraction time appeared a useful alternative of systolic time intervals for a semiquantitative evaluation of pulmonary pressure. In three patients, in whom these parameters couldn't be used, a qualitative judgement was possible on the the basis of the absence of a wave and the presence of a midsystolic closure of pulmonary valve.
