AIMS The aim of our study was to detect chronic total occlusion of the left anterior descending coronary artery (LAD), circumflex coronary artery (Cx), and right coronary artery (RCA) using transthoracic echocardiography (TTE) in 110 consecutive patients who underwent coronary angiography for investigation of angina. METHODS AND RESULTS Coronary blood(More)
AIM AND METHODS The role of simultaneous transesophageal Doppler assessment of coronary flow reserve (CFR) in the left anterior descending artery (LAD) and coronary sinus (CS) in the diagnostics of hemodynamically significant LAD stenoses of various localization was studied in 16 CAD patients with angiographically proven >50% stenotic atherosclerosis of the(More)
AIM AND METHODS The possibility of using multiplane transoesophageal echocardiography (TEE) and quantitative coronary angiography (QCA) in the diagnostics of stenotic atherosclerosis of the main coronary arteries in a comparative aspect were studied in 94 patients with coronary artery disease (men, mean age 52 +/- 7 years). Coronary arteries stenoses were(More)
AIM AND METHODS The role of transesophageal Doppler assessment of coronary flow reserve (CFR) in the coronary sinus (CS) in the diagnostics of significant left coronary artery (LCA) stenoses was studied in 65 CAD patients with angiographically proven >50% stenotic atherosclerosis of the LCA territory (38--with isolated left anterior descending artery (LAD)(More)
AIM: To elucidate possibilities of multiplane transesophageal ultrasound for assessment of localization and structure of atherosclerotic plaques in the thoracic aorta as well as relationship between changes of elastic-tonic properties, processes of aortic wall remodeling, stage of aortic atheromatosis, and coronary atherosclerosis. MATERIAL: Patients with(More)
AIM To compare antianginal efficacy and tolerability of propranolol therapy in patients with stable angina pectoris and chronic hypotension (Hpts) and normotensive patients with angina of effort (Npts). MATERIAL AND METHODS A randomized, single-blind, placebo-controlled study was made in 35 Hpts and 38 Npts was made using bicycle exercise tests,(More)
Quantitative coronary angiography remains the reference standard for assessing coronary anatomy, measuring anatomic severity of the stenotic lesion and assisting in the process of intracoronary interventions. Thus, treatment of coronary artery disease (CAD) is performed primarily on the basis of anatomic measurements of stenosis severity, although the(More)
Comparison of velocity parameters of blood flow and absolute coronary reserve (absCR) in the left anterior descending and posterior interventricular coronary arteries (ADCA and PICA) with calculation of relative coronary reserve (relCR) and determination of its normative values was carried out with the help of transthoracic echocardiography in 29 healthy(More)
AIM To elucidate the role of evaluation of coronary reserve in coronary sinus by transesophageal doppler for assessment of efficacy of various revascularization interventions. MATERIAL AND METHODS Patients with isolated stenoses of either left anterior descending or circumflex coronary artery subjected to stenting (n=14) and with two vessel disease(More)
