STUDY OBJECTIVES This study was conducted to evaluate to what extent the cardiopulmonary bypass (CPB) procedure in patients undergoing coronary artery bypass grafting (CABG) contributes to the systemic inflammatory response. Therefore, we measured bactericidal permeability increasing protein (BPI) as an indicator of neutrophil activation, interleukin 6 as… (More)
OBJECTIVES Patients in heart failure with left bundle branch block benefit from cardiac resynchronization therapy. Usually the left ventricular pacing lead is placed by coronary sinus catheterization; however, this procedure is not always successful, and patients may be referred for surgical epicardial lead placement. The objective of this study was to… (More)
Little information is available regarding the incidence of aortic dissection after previous aortic valve replacement (AVR), and factors associated with its development. Therefore, a meta-analysis of the literature was performed, and a patient population was studied retrospectively. Data from published studies showed that 87% of 31 patients were men (mean… (More)
BACKGROUND Hemodynamic assistance with a miniature intracardiac pump may fill the treatment gap between use of an intraaortic balloon pump (IABP) and the current, more invasive ventricular assist devices. The objective of this study was to compare the hemodynamic efficacy of a miniature intracardiac pump device with that of IABP. METHODS AND RESULTS… (More)
Right-sided circulatory failure (RSCF) is a serious complication in 15-30% of patients receiving a left ventricular assist device (LVAD). It is hypothesized that left ventricular support which lacks physiologic properties predisposes to RSCF. An integral computer simulation and experimental validation protocol was performed. The results suggest that with… (More)
OBJECTIVE This study was designed to clarify whether myocardial substrate uptake and oxidation change after a period of hypothermic cardioplegic arrest during coronary artery bypass grafting procedures. METHODS In 30 patients arterial and coronary sinus blood was sampled and coronary sinus flow measurements were performed before and after sternotomy and… (More)
We evaluated the feasibility to correlate intra-tumour heterogeneity as visualized on 18F-FDG PET with histology for NSCLC. For this purpose we used an ex-vivo model. The procedure was feasible in all operated patients. We have shown that this method is suitable for correlating intra-tumour heterogeneity in tracer uptake with histology.
BACKGROUND Recurrent thoracic empyema in the presence of residual lung tissue can be treated with an open window thoracostomy (OWT). Vacuum-assisted closure (VAC) of these large thoracic defects is a novel option. METHODS Nineteen patients with residual lung tissue received an OWT for treatment of recurrent thoracic empyema. In this retrospective case… (More)
PURPOSE This study was designed to compare the reaction of the vessel wall after application of the Hydrolyser hydrodynamic thrombectomy device to the reaction after use of a balloon thrombectomy catheter. The influence of the vessel inner diameter on vessel wall reaction was evaluated after passage of the Hydrolyser. MATERIALS AND METHODS After… (More)
Because of multiple ventricular lead fractures with inappropriate shocks, a 31-year-old male received a completely subcutaneous implantable cardioverter defibrillator (ICD) system with the already existing 'endocardial' ICD functioning as an atrial pacemaker.
