Flow-mediated vasodilation (FMD) of systemic arteries, a non-invasive parameter of endothelial function, is correlated with cardiovascular risk factors. The relationship between FMD and morphologically and clinically evident coronary artery disease has not been described. This study was performed to test the hypothesis that an impairment of FMD in the(More)
BACKGROUND To evaluate initial multicenter results with minimally invasive transapical aortic valve implantation (TAP-AVI) for high risk patients with aortic stenosis. METHODS AND RESULTS TAP-AVI was performed via a small anterolateral minithoracotomy with or without femoro-femoral extracorporeal circulation (ECC) on the beating heart. A pericardial(More)
OBJECTIVES In the Euroinject One phase II randomized double-blind trial, therapeutic angiogenesis of percutaneous intramyocardial plasmid gene transfer of vascular endothelial growth factor (phVEGF-A(165)) on myocardial perfusion, left ventricular function, and clinical symptoms was assessed. BACKGROUND Evidence for safety and treatment efficacy have been(More)
BACKGROUND Combined intracoronary and intramyocardial administration might improve outcomes for bone-marrow-derived stem cell therapy for acute myocardial infarction (AMI). We compared the safety and feasibility of early and late delivery of stem cells with combined therapy approaches. METHODS Patients with left ventricular ejection fraction less than 45%(More)
Magnetic resonance imaging (MRI) of the thoracic aorta, including cine-MRI, was performed in 25 patients suspected of having dissection of the thoracic aorta. MRI was correlated with echocardiography, CT and angiography. The sensitivity of MRI (100%) was most closely followed by CT and angiography (83% and 77% respectively). The specificity of MRI and(More)
Since 1980 cardiac manifestations of Lyme borreliosis have been described as selflimited conduction and transient left ventricular disorders or even cardiomegaly. An etiologic role of Borrelia burgdorferi in long-standing chronic heart disturbances is suggested by the cultivation of a strain of Borrelia burgdorferi which we were able to isolate from an(More)
A decrease in the fibrinolytic potential, mainly due to an elevation of plasminogen activator inhibitor (PAI), has been described in patients with stable coronary artery disease and a previous myocardial infarction. We investigated plasma levels of PAI and tissue plasminogen activator (t-PA) and their possible circadian variations in patients with unstable(More)
To explain the incidence and significance of mitral and aortic valve calcification and calcific deposits in the myocardium, a prospective echocardiographic study was performed with 21 consecutive patients who had primary hyperparathyroidism (PHP) and with 21 age- and sex-matched control subjects with normocalcemia. Calcific deposits in the myocardium were(More)
To evaluate the potential of magnetic resonance imaging (MRI) in detection and quantification of mitral regurgitation, 26 pts. with echocardiographically or angiographically documented mitral regurgitation were examined using a 0.5 Tesla superconducting magnet. In each patient a multislice-multiphase study in a sagittal-coronal double angulated projection(More)
BACKGROUND In the setting of primary percutaneous coronary intervention, patients with a chronic total occlusion in a non-infarct related artery were recently identified as a high-risk subgroup. It is unclear whether ST-elevation myocardial infarction patients with a chronic total occlusion in a non-infarct related artery should undergo additional(More)
