These are complex congenital heart diseases that occurs via embryological ventriculoarterial discordance. Digital subtraction angiography is considered to be the gold standard initial modality for these patients, with risks of invasive nature and high radiation dose. Now, magnetic resonance imaging is a promising imaging modality because of its radiation-free nature. Electrocardiographically (ECG)-gated 384 dual-source computed tomography (DSCT) with high temporal resolution, low radiation doses, and excellent image quality has evolved into a reliable tool for pediatric patients giving motion free images in the single cardiac...

All the CT scans were performed with latest 384 slice dua source dual energy MDCT ( Seimens Force) with ECG triggering. Most of the pateints were done under sedation. Many factors such as type of contrast, volume, route and method of adminstration influenced the quality of CT acquistion. We analysed around congenital heart disease patients done in our department from October 2016 to October 2018. We found 3 Case of DIRV, 216 cases of DORV, 22 cases of DILV, 6 cases of DOLV.

Various morphological features (situs, atrio-ventricular concordance, great vessel relationship and size of ventricles) were assessed in addition to common associations of each condition Double outlet left ventricle(DOLV)is an extremely rarecongenital cardiac anomalywhere both theaortaandpulmonary trunkarise from the anatomicalleft ventricle.It is usually classified as aconotruncal anomaly and is often associated with aventricular septal defect with normal continuity between theaortic valveand anteriormitral valve. most common associations are ventricular septal defects,a subpulmonic and subaortic obstruction. Double inlet left ventricle (DILV) is a heart defect that is present from...

MDCT can give morphological assessment of these conditions and help in planning surgery. It is especially useful for extra-cardiac structures which are not well seen on ECHO. It not only assess cardiac anatomy, but also assess pulmonary artery, coronaries and tracheobronchial tree.
