BACKGROUND The application of axial-flow pumps in patients with end-stage heart failure reveals a significantly reduced infectious complication rate as compared with rates observed with pulsatile devices. The remaining adverse event rate relates mainly to thromboembolic complications with neurologic consequences. We investigated the dependence of the(More)
BACKGROUND During unilateral selective cerebral perfusion (SCP), via cannulation of the brachiocephalic trunk, the brain receives blood only through the right common carotid artery and the right vertebral artery. For perfusion of the contralateral (left) hemisphere it is counted on the competence of the circle of Willis (CoW). It is well known that(More)
PURPOSE To report a rare case of dissecting thoracic aortic aneurysm in a young patient with Turner syndrome owing to complete or partial monosomy of the X chromosome. CASE REPORT A 22-year-old patient with Turner syndrome presented with a 2-month history of voice loss and dysphagia. Multislice computed tomography (MSCT) disclosed a large (53x75-mm)(More)
In idiopathic membranous nephropathy (IMN) immunosuppressive therapy should be reserved for patients with potential risk factors at baseline or who show a progressive course. Cyclophosphamide pulse therapy (CPT) in IMN is not yet widely tested. We carried out a trial of CPT combined with conventional treatment in a group of patients with IMN at a greater(More)
When a donor heart is not available during the end stage of heart failure, the implantation of a ventricular assist device is the only therapeutic alternative. Many such devices are designed to provide circulatory support to adults, but very few are available for children and infants, especially in the United States. In children, implantation of ventricular(More)
OBJECTIVES The optimal surgical technique for correction of left ventricular aneurysms is still debated. This study compares the midterm results achieved with linear resection or endoventricular repair. METHODS In the period February 2002-February 2004 forty-five consecutive patients with anterior LVA have been operated. The patients were divided in two(More)
The Berlin Heart INCOR system (Berlin Heart AG, Berlin, Germany) is a left ventricular assist device that generates a laminar blood flow. One of our INCOR-implanted patients was admitted to the hospital with clinical data indicating device thrombosis. The flow through the pump was assessed by contrast injection into the inflow canula. Lack of flow through(More)
Finite impulse response (FIR) filter is the key functional block in DSP (Digital Signal Processing) designs and nearly always form the starting point for analyzing an architecture. This paper contains a new filter architecture, along with FPGAVirtex-4 (Xilinx) and XtremeDSP (DSP48) slice. The XtremeDSP slice is a high performance multiplier and arithmetic(More)
