Modern possibilities of computed tomography as a part of diagnosis of heart diseases and coronary arteries
Today CT-coronary angiography is a minimally invasive method, alternative to invasive coronary angiography, for coronary arteries permeability evaluation. This method allows defining a majority of myocardial ischemia causes, including variants and coronary arteries abnormal development, visualizing myocardial structural changes, receiving data on contraction function of the heart, and on possible causes of myocardial ischemia in case of the absence of coronary artery disease (atherosclerosis). CT-coronary angiography is the only minimally invasive method for quantitative evaluation of the coronary arteries lumen, which may replace invasive coronary angiography. But quantitative evaluation of lesion as the only method doesn't allow defining its hemodynamic relevance. For the appropriate tactics of treatment and planning of heart revascularization CT-coronary angiography should be accompanied by methods, which approve hemodynamic relevance of lesions or myocardial ischemia.
