COMPUTED TOMOGRAPHY IN THE DIAGNOSIS OF CONGENITAL HEART DISEASE

Abstract

Aim of the study – Evaluate the value of multispiral computed tomography (MSCT) with intravenous contrast in the diagnosis of congenital heart disease (CHD) at the stage of preoperative preparation and choice of surgical tactics. Methods. Between January 2021 and June 2022, 30 CT cardiographies were performed in our center, of different age and mediastinal pathology. A 64-slice Somaton Siemens sensation 64 CT scanner complete with digital processing systems was used. The main vessels of the heart were examined with intravenous bolus injection of contrast agent. Image analysis included study of anatomy of the defect by three-plane tomograms and construction of multiplanar 3-D reconstructions. Results. Modern approaches to the imaging diagnosis of CHD in all age groups are presented. The role of CT-angiography with intravenous contrast in the diagnosis of congenital, acquired cardiovascular and thoracic pathology is shown. Qualitative assessment of CT-angiographic picture of CHD was performed. Conclusion. Our experience with CT cardiography in the examination of patients with CHD, in contrast to traditional ultrasound and invasive techniques, in most cases allows to obtain more valuable diagnostic information, especially extracardiac structures, which determines its significance in the examination of CHD. It details anatomy of malformations in reliable morphometric indices, diagnosis of aortic, pulmonary artery, right ventricular pathology, including pathology of its outflow tract, to assess ventricular-artery connections and atrialventricular connections.
