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)
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)
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)
Growing evidence suggests that poor coronary blood flow after primary percutaneous coronary intervention (PCI) is associated with unfavorable clinical out-come. We retrospectively evaluated data from our single center “real world patients” database of patients undergoing primary PCI to determine differences in clinical and angiographic patterns in patients(More)

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)
BACKGROUND AND PURPOSE Abciximab has been shown to significantly reduce thromboembolic complications of coronary artery stenting. A prospective, randomized study was performed to test whether abciximab has comparable beneficial effects in carotid artery stenting. METHODS Seventy-four consecutive patients undergoing elective stenting of the carotid artery(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)
Patients with symptomatic > or = 60% (n = 134), asymptomatic > or = 80% (n = 143), and asymptomatic progressive > or = 60% (n = 25) internal carotid artery stenosis underwent stenting and were followed clinically and by Doppler-assisted duplex imaging for 27.1 +/- 15.6 months. Stroke and death from stroke occurred within 30 days after stenting in 4.7% of(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)
