| Popis: | The presented clinical observation demonstrates the diagnostic capabilities of cardiac volumetric computed tomography (CT) with a pharmacological test by a vasodilator adenosine triphosphate (ATP) in the simultaneous assessment of coronary anatomy and changes in left ventricular myocardial perfusion (LV) in a patient with painless myocardial ischemia and coronary atherosclerosis. A 68-year-old patient with coronary heart disease (CHD) and atherosclerotic changes in the coronary arteries underwent cardiac volumetric CT in combination with a ATP pharmacological test. The study was performed on a Aquilion ONE 640 Vision Edition computer tomograph (Toshiba, Japan). Assessment of LV myocardial perfusion was carried out in comparison with other clinical, laboratory and instrumental examination methods. The results of clinical and instrumental examination of a patient with a low pre-test probability of coronary heart disease are presented. From the standpoint of modern recommendations on stable coronary heart disease, false-negative results of single-photon emission computed tomography of the heart and stress-echocardiography are discussed. Clinical observation demonstrates the feasibility of diagnosing LV myocardial ischemia by cardiac volumetric CT combined with ATP pharmacological test, confirmed by an invasive determination of the fractional flow reserve. The given clinical example represents the advantage of cardiac volumetric CT, combined with the ATP pharmacological test, as a method for visualizing LV myocardial perfusion in detecting myocardial ischemia. |
