OBJECTIVES Few studies have examined the use of stentless Freestyle bioprostheses in patients with active valve endocarditis (VE). The aim of this study was to evaluate outcomes of stentless Freestyle bioprostheses in patients undergoing full-root replacement. METHODS From February 2000 to June 2010, 180 patients with VE underwent cardiac surgery at our(More)
BACKGROUND Pulmonary hypertension (PH) is a well-known independent risk factor for mortality and morbidity after cardiac surgery. However, no weight is given to PH in the current guidelines for the management of patients with aortic stenosis (AS) undergoing aortic valve replacement (AVR). The aim of our study was to evaluate the impact of preoperative PH on(More)
This work presents the development of a demonstrator for testing the performance of Multisensor Data Fusion applied to Naval Target Classification; the model used for demonstration has been developed by the authors for comparing different algorithms and techniques with special attention to Fuzzy Logic influence. Although this project is not classified, some(More)
The authors propose an approach for developing complex models integrating different components and including human behaviour; in these problems the data uncertainty as well as their availability is a major criticality; the paper proposes an approach for a mutual validation of the model and a fine tuning process based on integrating simulation with(More)
This paper is focused on the development of a model for applying Reliability Centred Maintenance (RCM) on complex system by integrating simulation and artificial intelligence (AI); the application is related to maintenance planning of groups of gas turbine power plants. This paper will explain the reasons, the criticalities and the lessons learned during(More)
AIMS To present the results of a novel technique of aortic valve decalcification (AVD) in a consecutive population of elderly patients with severe aortic valve stenosis (AVS) and small aortic annulus. METHODS Between January 2008 and December 2012, a consecutive series of 34 patients (mean age 80 ± 13 years) with severe AVS were operated on using AVD.(More)
