This paper suggests tools that provide significant improvements in the design and verification of FPGA-based digital circuits. These tools include reusable specifications of hardware components (modules) that have been proposed for two types of CAD environments; Xilinx ISE 5.x and Celoxica DK1. The components can be employed to implement both(More)
This paper describes the developed hardware/software tools, libraries and design methods for FPGA-based embedded systems which include: a kernel prototyping board with the Xilinx Spartan 3 FPGA; a set of projects for reusable FPGA-based circuits; utilities for FPGA programming; software/hardware tools that provide support for reconfiguration; and programs(More)
BACKGROUND The revascularization strategy of the left main disease is determinant for clinical outcomes. OBJECTIVE We sought to 1) validate and compare the performance of the SYNTAX Score 1 and 2 for predicting major cardiovascular events at 4 years in patients who underwent unprotected left main angioplasty and 2) evaluate the long-term outcome according(More)
BACKGROUND Fewer bleeding complications and early ambulation make radial access a privileged route for cardiac catheterization. However, transradial (TR) approach is not always successful, requiring its conversion into femoral access. OBJECTIVES To evaluate the rate of conversion from radial into femoral access in cardiac catheterization and to identify(More)
BACKGROUND The clinical benefit of percutaneous coronary intervention (PCI) for long coronary lesions is unclear; furthermore, concerns have been raised about its safety. OBJECTIVES To evaluate the predictors of major adverse cardiac events (MACE) associated with PCI using a full metal jacket (FMJ), defined as overlapping drug-eluting stents (DES)(More)
Moderate-to-severe paraprosthesic leak causing hemodynamic deterioration and left ventricular remodeling can occur after transcatheter aortic valve implantation (TAVI). We present the case of a 75-year-old woman who underwent TAVI with a 26 mm CoreValve prosthesis complicated with an acute left ventricle dilatation due to a severe paravalvular leak. Patient(More)

1 H and 195 Pt NMR are used to probe the spin ½ anion chain in the quasi-one-dimensional conductor Per 2 [Pt(mnt) 2 ], which exhibits nearly simultaneous charge density wave (CDW) and spin-Peierls (SP) transitions at low temperatures (T c ~ 8 K). Below T c the [Pt(mnt) 2 ] chain forms a spin-singlet state that is evident in 1 H NMR spectra and spin(More)
The paper discusses an FPGA-based prototyping system with both wired and wireless programming and data exchange facilities. The system can be efficiently used for different types of portable devices. For example, it can supply additional interfaces to mobile computers; can be seen as a hardware accelerator for solving computationally complex problems or(More)
