CARDIOVASCULAR JOURNAL OF AFRICA • Volume 35, No 2, May – August 2024 128 AFRICA particularly for preprocedural planning of difficult coronary artery catheterisation.6,7 We chose CCTA as the primary option for evaluating patients with SIT due to the anticipated challenges involved in performing ICA in the presence of dextrocardia before advanced examination and treatment, such as percutaneous coronary intervention or CABG. Fig. 1. A. Volume-rendered CT images from the anterior view show the heart as a mirror image, with the cardiac apex located on the right. RCA: right coronary artery, LAD: left anteror descending artery, LCx: left circumflex artery, D1: first diagonal branch. B. Intra-operative image of dextrocardia. B. Intra-operative image of dextrocardia. A B Fig. 2. A. Axial image through the upper abdomen showing the liver (L) in the left upper quadrant and spleen (S) in the right upper quadrant. B. Axial image at the level of the cardiac chambers shows the morphological left atrium (LA) is connected to a morphological left ventricle (LV), and the morphological right atrium (RA) is connected to a morphological right ventricle (RV). Continuity between the left ventricle and the left ventricular outflow tract is seen. The desecending aorta (DA) is located in the right hemithorax. A B
