Concerns exist in the field of transcatheter aortic valve implantation regarding the treatment of patients with mechanical mitral valve for possible interference between the percutaneous aortic valve and the mechanical mitral prosthesis. We report our experience with percutaneous aortic valve implantation in 4 patients with severe aortic stenosis, previously operated on for mitral valve replacement with a mechanical prosthesis. All patients underwent uneventful percutaneous retrograde CoreValve implantation (CoreValve Inc, Irvine, CA). No deformation of the nitinol tubing of the prostheses (ie, neither distortion nor malfunction of the mechanical valve in the mitral position) occurred in any of the patients. All patients are alive and asymptomatic at a mean follow-up of 171 days.

    ABSTRACT: Transcatheter aortic valve implantation (TAVI) has shown favorable outcomes in patients with severe symptomatic aortic valve stenosis who are at high surgical risk or are unsuitable candidates for open heart surgery. However, concerns exist over treating patients who have previously undergone mitral valve surgery due to the potential interference between the mitral prosthetic valve or ring and the TAVI device. In this case report, we present a patient with symptomatic severe aortic stenosis and previous mechanical mitral valve replacement who was successfully treated with TAVI using a CoreValve.

    ABSTRACT: The increasing capabilities of todays LSI-technology have raised the interest in complex building blocks (RAM, ROM, microprocessor, etc.) for use in large electronic systems. We believe that a content addressable memory (CAM, refs 1-3) is such a standard function too. Much information-processing is performed by means of tables. By using a CAM, table searching can be done efficiently in the memory, thus moving some software routines to the hardware level. Yet there is no generally accepted standard for a CAM. The existing CAM chips generally contain only an array of memory cells without any control circuitry. Moreover reading and writing is done in the same way as in a RAM : the information must be accompanied by the address of the physical location to be used. In this paper we present a new approach to the concept of a CAM, suitable for integration.

    ABSTRACT: Operation support systems have traditionally been operatorsupport systems, designed and built to aid the traditional monitoring-oriented individual operator in his or her work. Focus has been mostly on the natural science and engineering aspects of the problem, addressing functions such as fault detection, alarm filtering, diagnosis, estimation and optimization of the physical process.These are necessary, but not sufficient, aspects of productive operation support systems for the future: In the process industry there are strong incentives for a change towards integration of shift- and daytime work, and towards integration of operation and maintenance functions. As a result, the nature of process operation work is presently changing from being decomposed individual functional jobs, towards collaborative efforts through self-sufficient shift-teams. These shift-teams must be multidisciplinary to be able to perform their jobs. Now, the operators' work is becoming a multi-task job rather than proficiency in a set of fixed and well-defined tasks. Individual and organizational learning and development are becoming key expectations which the new kind of operating organizations have to face.An important concern in this new and rapidly changing situations, is to design and implement a suitable operation support system, and how this is to be accomplished.This paper addresses one industrial case, and describes how the above challenges have been approached. The case is a hydrogen peroxide plant located in western Canada which organizes the production according to the characteristics described above. This plant has also implemented an integrated information system. The organization emphasizes the importance of creating arenas for learning during both design, implementation and utilization.
