BACKGROUND Renal denervation (RDN) has been shown to reduce blood pressure in patients with resistant arterial hypertension (RAH). We aimed to investigate predictors for response to RDN. METHODS Patients suffering from RAH underwent RDN after exclusion of secondary causes of hypertension. Ambulatory blood pressure measurement (ABPM) for 24 h was performed(More)
AIMS Left ventricular function may be altered by right ventricular apical pacing. The aims of the study were to compare the long-term course of different parameters of left ventricular dysfunction in patients undergoing implantation of a dual-chamber pacemaker with the ventricular lead in a septal position vs. in a standard apical position. METHODS We(More)
The aim of this retrospective study was to determine the incidence of stent loss during interventional procedures and to identify the associated immediate and long-term consequences of such loss. We evaluated 36 cases in which the stents were prematurely displaced from the stent delivery device. Five stents were completely removed from the vascular system(More)
BACKGROUND There is increasing evidence that transplantation of autologous stem cells improves cardiac function after acute myocardial infarction (AMI). For propagation of peripheral blood stem cells (PBSCs), application of granulocyte-colony stimulating factor (G-CSF) has been shown to be feasible, effective, and safe. We sought to evaluate a clinical and(More)
OBJECTIVE To assess the incidence, morphology, and associated clinical symptoms of coronary artery disease in patients undergoing elective carotid artery stenting. METHODS In a prospective observational study at a tertiary care centre (university teaching hospital) 444 consecutive patients underwent elective stenting of the carotid artery. Twenty four(More)
BACKGROUND Device replacements bear many potential risks for patients. Electrocautery should be used cautiously because of heating of the cautery tip which may lead to insulation melting. The PEAK PlasmaBlade™ (Medtronic Inc., Minneapolis, MN, USA) uses a novel technology to cut tissue. The objective of this study was to evaluate if this instrument is less(More)
BACKGROUND Ibutilide is a class III antiarrhythmic drug, frequently used for conversion of atrial fibrillation and flutter. Retrospective cohort evaluations found that intravenous application of magnesium enhances the efficacy of ibutilide for chemical conversion of these arrhythmias. This prospective study sought to investigate the effects of intravenously(More)
BACKGROUND Permanent cardiac pacemakers have historically been considered a contraindication to magnetic resonance imaging (MRI). OBJECTIVE The purpose of the ProMRI/ProMRI AFFIRM Study, which was a multicenter, prospective, single-arm, nonrandomized study, was to evaluate the clinical safety of the Biotronik ProMRI Pacemaker System under specific MRI(More)
BACKGROUND Following stenting for acute myocardial infarction, transcoronary transplantation of granulocyte-colony stimulating factor (G-CSF) mobilized autologous stem cells (ASC) has been shown to result in an increased in-stent restenosis rate of bare metal stents (BMS). HYPOTHESIS This study sought to compare the extent of neointimal growth in BMS and(More)
Transcoronary transplantation of autologous stem cells (ASC) can improve cardiac function after myocardial infarction. For ASC-propagation, granulocyte-colony stimulating factor (G-CSF) is widely used. However, a clinical long-term safety profile of combining G-CSF therapy and transcoronary ASC-transplantation does not exist. We report on three cases of(More)
