Abstract:
The aim of this study ware to assess the appearance of the coronary artery (appearance, pathological change and the most coronary artery effect by pathology) by using multi-slice CT angio (CT scan 64 slice) and cardiac catheterization and to know the best way to do this exam and to know the importance, characteristic and limited from the other exam witch evaluate the risk factor in coronary artery. . Study was done in Royal scan center in Khartoum and retrospective data from King Fahad cardiac center in Kingdom of Saudi Arabia “Riyadh”. The study sample was 50 patients, 30 of them underwent to CCTA and 20 of them underwent to cardiac catheterization by vein. . In the study the positive patient who diagnosed by CCTA were 17(56.6%) from CCTA group 11(64.7%) of them have Ca deposits, 4(23.5%)have coronary artery stenosis and 2(11.7%) have congenital anomalies. the rest of the CCTA group are normal in configuration. . The positive patient who diagnosed by cardiac catheterization 6(30%) from this group have Ca stenosis, the rest of the group are normal. . Also the capable to diagnose many type of pathology by use CCTA like calculate Ca scoring in any coronary artery witch that difficult to detect by cardiac catheterization and other exams specifically and that cannot complete the CCTA if it’s in high level because there are more risk factor and guaranty the image quality. The study showed that the most affected branches were as follows LAD have the most risk factor by any why that risk in percentage 43.50% , RCA 30.40% , LCX 21.7% , LMA 4.4% the lasted one is PDA in percentage near to zero.
Both technique (CCTA and cardiac catheterization) perform good visualized of larger coronary arteries branches, but cardiac catheterization visualized smaller branches better than CCTA.
