fig1
A large secundum atrial septal defect (ASD) with left to right shunt was evident (Figure 1) with a calculated pulmonary-to-systemic blood flow ratio (Qp/Qs) estimated at 2.3 to 1.
Cardiac computed tomography showing the large secundum atrial septal defect (green arrow) as well as the dilated right atrium (RA) and right ventricle (RV); LA (left atrium), LV (left ventricle).

The CTCA demonstrated a large ASD along with a dilated right ventricle and right atrium (Figure 2).
Curved multiplanar reformat of computed tomography coronary angiography demonstrating the anomalous left main coronary artery (green arrows) arising from the right coronary cusp then traversing between the aorta and the pulmonary trunk before bifurcating into the left anterior descending and circumflex arteries. LA (left atrium), LV (left ventricle).

The left main coronary artery was seen to arise from the right coronary cusp then traverse between the pulmonary trunk and the proximal ascending aorta before bifurcating into the left anterior descending and circumflex arteries, which then followed their normal courses distally (Figures 3 and 4).
Three-dimensional reconstructed, volume rendered computed tomography coronary angiography showing the course of the anomalous left main coronary artery (green arrows) arising from the right coronary cusp then traversing between the aorta and right ventricular outflow tract (RVOT).
