In patients with coronary artery disease including those after coronary bypass graft operation and heart transplantation intervention studies based on serial quantitative coronary angiography, in part combined with intravascular ultrasound, are of increasing relevance. Since vasomotor tone of epicardial coronary arteries is influenced by a variety of(More)
The absence of angiographic findings despite significant coronary artery disease has been previously described. Possible explanations for the limitation of plaque detection by angiography include compensatory vessel enlargement in face of intracoronary plaque formation, the lack of reference segments in diffuse atherosclerosis as well as technical(More)
Several reports have established the concept of nitric oxide synthase (NOS) gene transfer for inhibiting smooth muscle cell (SMC) proliferation after vascular injury. To minimize potential risks associated with viral gene transfer, we developed a liposome-based gene transfer approach employing inducible NOS (iNOS) overexpression for inhibition of(More)
Unselective and β_1-selective beta-blockers may induce vasoconstriction of normal and stenotic epicardial coronary arteries. To analyze the influence of the vasodilatory beta-blocker celiprolol on coronary vasomotility, 0.4 mg celiprolol/kg were intravenously infused over 4 minutes in 13 patients with coronary artery disease. Coronary angiograms were taken(More)
IVUS imaging provides a 2-dimensional, cross-sectional view into the lumen and vessel wall structure of coronary arteries; it is superior to angiography with regard to visualization about several aspects of coronary artery disease. IVUS has given important information on the development and progression of coronary atherosclerosis. Moreover, IVUS has(More)
A number of treatment approaches exist for excessive flowrate arteriovenous fistulae. Banding has a number of advantages, yet there is concern over its use due to reported high post-surgery thrombosis rates. A computational study is conducted of a new technique, to elucidate the hemodynamics present in the process. The key improvement involves the use of an(More)
