MSCT correctly detected TGA in 75 patients (93,75%) out of 80 in whom surgeon or invasive cardiac catheterization had identified TGA, with a sensitivity, specificity and negative predictive value of 100%. 5 cases of false negative results were received, which were confirmed on ECHO subsequently. 

  • Results of CT and ECHO matched in 69 (92%) patients.
  • Gender ratio presents predominance of 45 (60%) males over 30 (40%) females.
  • 61 patients (79%) had D-TGA (21%) and 14 patients had L-TGA only.
  • The majority of patients have been identified under the age of 1 month.
  • 61 patients (79%) had D-TGA (21%) and 14 patients had L-TGA only.
  • 64(85%) patients from 75 were operated, but in 11(14%) from them died. 

In all 75 patients TGA combined with different CHD, such as

  1. Patent ductus arteriosus (PDA) in 43 patients(61.4%)
  2. Ventricular Septal Defect (VSD) in 33 patients(57.3%)
  3. Atrial Septal Defect (ASD) in 27(44.0%)
  4. Single ventricle (SV) in 23(30.7%)
  5. Patent foramen ovale (PFO) in 21(28.0%)
  6. Atrioventricular septal defect (AVSD) in 11(14.7%)
  7. Single atrium (SA) in 7(9.3%)
  8. Anomalous pulmonary venous drainage (APVD) in 5(6.7%)
  9. Interrupted aortic arch (IAA) in 3 cases(4%).
