Determination of Sensitivity and Specificity of High Resolution CT Scan in Evaluation of Cardiac and Extra-Cardiac Anomalies among Bangladeshi Children

Congenital heart disease (CHD) is one of the important causes of morbidity and mortality in the pediatric age group. Invasive angiography is considered as gold standard method for the diagnosis of pediatric cardiovascular diseases. Multi-detector CT cardiac angiogram by using 64 slice scanner is a useful modality and suitable alternative to previous invasive procedure in evaluation of congenital heart disease. The present study was conducted in the Department of Cardiology of NICVD during the period of September 2019 to August 2020 (One year). We selected 40 patients presenting in the outpatient department of National Institute of Cardiovascular Diseases and Hospital (NICVD) who were diagnosed to have congenital heart disease clinically and radiologically. CT angiogram revealed ASD in 10%, coarctation of aorta in 5%, Pentalogy of Fallot in 2.5%, Tetralogy of Fallot (TOF) in 32.5%, Ventricular septal defect (VSD) in 30.0%, PAH in 2.5%, PS in 5%, RVH with PS in 2.5%, PDA in 5% and Tricuspid atresia with ASD with VSD with PS in 2.5% patients. Conventional catheter angiogram revealed ASD in 5%, VSD in 32.5%, TOF in 30%, PS in 12.5%, Coarctation of aorta in 5% and Pentalogy of Fallots in 5%. The diagnostic performance of MDCT in the diagnosis and evaluation of congenital heart disease was high.
