SUMMARY
Coronary computed tomography angiography (CTA) is the first non-invasive imaging
technique that allows the evaluation of the lumen and walls of the coronary
arteries. The sensitivity in defining significant stenosis (>50% caliber
reduction) is 93% for the evaluation of single vessels. This is a method for
determination of the so-called Calcium score. With a coronary artery calcium
(CAC) score >400, the incidence of coronary episodes rises ten-fold. The method
can also be used in the evaluation of bypass patency. The first case report
shows a patient with irregular heart rhythm and chest pain. After 24h, the
holter ECG monitoring and stress echocardiography test, multislice computed
tomography (MSCT) examination were performed, excluding thus the coronary
disease. The second case report presents a patient who, after coronary artery
by-pass grafting, had a positive exercise test. MSCT examination showed the
occlusion of three grafts and arteria coronaria dextra. While coronary MSCT is
still an emerging technology, in the next decade, undoubtedly, it will become a
major cardiovascular imaging option.
