Abstract

Retrospective descriptive study to survey and compare the results of echocardiography and cardiac multi-slice computed tomography (cardiac MSCT) with total anomalous pulmonary venous connection; performed on 33 pediatric patients to the diagnosis TAPVC based on surgical results at the National Children's Hospital from January 2022 to August 2024. Results: Echocardiography and MSCT accurately diagnosed 100% of patients with  total anomalous pulmonary venous connection. MSCT has a sensitivity of 100% in diagnosing abnormal types, higher than echocardiography from 0% to 100%). Cardiac MSCT has a sensitivity and specificity of 100% in diagnosing the subcardiac location, higher than echocardiography (37.5%, 37.5%). Cardiac MSCT has a sensitivity and specificity of 100% in diagnosing obstruction, higher than echocardiography (86.7%, 66.7%). Conclusion: Cardiac MSCT is a valuable method of diagnosing abnormal pulmonary venous return. In some urgent cases, the value of ultrasound in the initial diagnosis cannot be denied. Therefore, these two methods should be combined for quick, accurate and comprehensive assessment.
