ABSTRACT

Introduction: The coronary artery disease is a heterogeneous illness in which fibrous stable lesions may appear; injuries rich in unstable lipids or both in the vascular walls. The mortality index due to the coronary artery disease in the West countries is very high, Mexico stands for the second place. This illness is also responsible for the 25% of deaths in the United States.
Objective: To show the technique of obtaining a Computerized Angiotomography of the coronary arteries, the artery coronary anatomy and the results that we have obtained in cases studied in our institution, in the search of coronary artery disease condition for the coronary stenosis.
Material and methods: 53 patients were selected, showing cardiovascular risk factors or artery coronary disease, to whom quantification of coronary calcium and Computerized angiotomography were carried out. A 16 slices TCMD, General Electric equipment was used. Vital Signs Monitoring Millenia 3500 CT. Advantage Windows 4.2 General Electric. Synchronized with EKG, FC was obtained, which ideally should be ‹ 70 x min. Later, the place of origin of the left coronary was selected and by means of the Timing Bolus technique, 40 mL was injected to 5 mL/seg contrast in order to determine the necessary delay to achieve a bigger contrast concentration. Also, new slices were made during the contrast injection with a volume of 90 mL and an injection range of 4-5 mL/seg with a 25-35 seg delay with the obtained value of TIMING Bolus. Finally, 3D, MIP, MPR reconstructions were made.
Results: Fifty two patients within a time period comprised between the 3/08/05 to 11/11/06. Thirty six patients were found with artery coronary disease (light 5, moderate 10, severe 21), 16 were normal.
We found six anatomical variants, from which three didn’t show pathological findings and three did. Seven presented BYPASS, eight presented Stent, 21 coronary stenosis. In 10 patients, were correlated with Gammagraphy and conventional coronariography CNG.
Conclusion: Computerized angiotomography of coronary arteries is a non-invasive imaging technique that appropriately deploys the arterial anatomy for the evaluation of the artery coronary disease.
