Late complications from vascular closure devices, such as puncture site stenosis, are not well documented. They may be of clinical significance and probably share the same mechanism that underlies intra-coronary stent restenosis. Thus, treatment approaches based on balloon angioplasty alone may not be sufficient, and the use of stents (when possible) is(More)
(1) To study the prevalence and severity of coronary artery disease (CAD) in diabetic patients. (2) To provide a detailed characterization of the coronary atherosclerotic burden, including the localization, degree of stenosis and plaque composition by coronary computed tomography angiography (CCTA). Single center prospective registry including a total of(More)
BACKGROUND Patients with coronary total occlusions are at especially high risk for restenosis and new revascularizations. Sirolimus-eluting stents dramatically improved the clinical outcome of this subset of patients in randomized trials, but other drug-eluting stents, mainly the everolimus-eluting stent (currently the most frequently used stent), have not(More)
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)
INTRODUCTION According to the current guidelines for treatment of ST-elevation myocardial infarction (STEMI), percutaneous coronary intervention (PCI) should be performed within 90 min of first medical contact and total ischemic time should not exceed 120 min. The aim of this study was to analyze compliance with STEMI guidelines in a tertiary PCI center. (More)
INTRODUCTION In recent years, various specific techniques and materials have been developed for the treatment of coronary chronic total occlusions (CTO). OBJECTIVE To evaluate the current situation in the treatment of CTO (techniques and material) in our setting. METHODS We evaluated data on techniques and material used in the CIBELES (ChronIc coronary(More)
BACKGROUND After an acute myocardial infarction, women have a higher risk of death or reinfarction. In unstable angina, female gender seems to be protective. On the other hand, studies suggest that women are less frequently given coronary angiography. OBJECTIVES To evaluate, in our population of patients admitted for non-ST-elevation acute coronary(More)
Electronic devices used in the scope of robotics and embedded systems have to be adapted to numerous external events and many of them might be unknown in advance. This application-specific particularity requires environment-specific adaptation and frequent changes in the pre-defined behaviour. In general, all feasible functionality cannot be incorporated in(More)
INTRODUCTION AND AIMS Percutaneous coronary intervention (PCI) is increasingly used as a treatment option for unprotected left main coronary artery (ULMCA) lesions. We aimed to evaluate the long-term outcome of patients undergoing ULMCA PCI. METHODS AND RESULTS We retrospectively analyzed 95 consecutive patients (median EuroSCORE I 2.9 [IQR 1.4;6.1]) who(More)
BACKGROUND The SYNTAX score is a useful tool to evaluate percutaneous coronary intervention risk regarding the number, complexity, and location of lesions. Despite its proven value in the prognosis of three-vessel disease, there are few data about its usefulness in other selected subsets of patients. This study aimed to evaluate the prognostic value of the(More)
