Purpose. The aim of the study was to present the possibilities of heart-axis-oriented computed tomography (CT) angiographic multiplanar reformations in diagnostics of pulmonary artery atresia. Results of CT-angiocardiography of 33 patients with pulmonary artery atresia aged from 1st day-of-life to 9 years old were retrospectively observed and analyzed. Analysis of heart-axis-oriented multiplanar reformations included atria and ventricles localization and morphology, system and pulmonary veins inflows, aorta and pulmonary trunk origins and relative position, visualization of the output portion of the right ventricle, mitral-semilunar fibrous prolongation, proportion of the heart chambers, presence of communications (opened oval window, interatrial and/or interventricular septum defect), the sources of lung perfu-sion, presence of concomitant pathologies. Of 33 patients with pulmonary artery atresia vari-ation with interventricular septum defect was detected in 21 patient (9 boys and 13 girls), with intact interventricular septum – in 12 patients (9 boys and 3 girls). Analysis of conse-quently performed heart-axis-oriented multiplanar reformations allows to detect peculiar an-atomic signs of pulmonary artery atresia, concomitant intracardial and extracardial patholo-gies. The most valuable signs of pulmonary artery atresia are detected in followed refor-mations: supply ventricle division reformation, left ventricle long-axis reformation and short axis reformation at the level of main arteries.
