http://www.ivs.no/ The Interventional Centre's Webpages EBA-News 2.0.0 On January 20th 2010 Lars Mathisen defended his thesis from the Interventional Centre and Dept. of Thorasic and Cardiovascular Surgery, Oslo University Hospital, Rikshospitalet and Faculty of Medicine, University of Oslo. The evaluation committee consisted of 1.opponent professor, Emerita Judy Watt-Watson, Centre for Advanced Studies in Professional Practice, University of Torointo, Canada, 2. opponent professor Rune Haaverstad, Dept. of Thorasic Surgery, Haukeland University Hospital and committee leader profesor Theis Tønnessen, Dept. of Thorasic Surgery, Institute for Hospital Medicine, University of Oslo. The dissertation was lead by the University representative professor Lars Gullestad from Department of Cardiology, Institute for Hospital Medicine, University of Oslo. The quality of life studies performed by Lars Mathisen was based on follow-up studies of patients enrolled in the Off-pump project, a randomized clinical trial comparing off-pump and on-pump coronary artery bypass surgery. So far 5 PhD's has been produced by this project material. Abstact; ”Patient-reported outcomes after on-pump and off-pump coronary artery bypass surgery” Patients’ self-report of symptoms, health status and overall quality of life reflects the experience of ischemic heart disease, as well as the impact of coronary artery bypass surgery (CABG).

The Minister met with leaders from Pharmaceutical industry including Karita Bekkemellem (The Association of the Norwegian Pharmaceuitical Industry-LMI), Gunnar Sæther (MSD), Erlend B. Smeland, leader of Research and Innnovation at OUS, Steinar Aamdal, MD, leader of the Clinical Research and Test Unit at Radiumhospitalet OUS and professor Erik Fosse from the Interventional Centre. Among topics discussed were how to improve collaboration between pharmaceutical industy and Norwegian hospitals and what role the government could play. One of the objectives of LMI is to increase the pharmaceutical research in Norway. After the meeting the Minister visited the clinical facilities at the Interventional Centre and was guided through the specialized operating rooms by research nurse Karl Øyri.

The abstract describes researh work performed at the Interventional Centre and is presented here: Hepatic and intestinal PCO2 measurement for real-time detection of hepatic artery and/or portal vein occlusion. Liver ischemia is a potentially life-threatening condition occurring in the course of liver transplantation, liver surgery and circulatory shock. Following liver transplantation hepatic artery (HA) stenosis and portal vein (PV) obstruction occur in 3 – 12 % of the patients, and more frequently in children than adults. Today, standard of care is Doppler ultrasound and liver enzyme assessment daily. Accordingly, detection of severe hypoperfusion may be delayed. Continuous monitoring of intrahepatic and intestinal PCO2 may be an opportunity for early detection of ischemia as tissue CO2 increases during ischemia by HCO3 buffering anaerobically produced lactic acid.Blood flow reduction in either HA, PV or both leads to alterations in intermediary metabolism in the liver. Intrahepatic and intestinal CO2 measurement as a marker for anaerobic metabolism detects these changes and enables correct diagnosis of the affected vessel.

This study examined why breakthroughs in knowledge may fail to be translated into medical practice. These novel practices often lack alignment with existing practices, or they cut across established professional boundaries and power structures. Despite this, we know that establishing practices across heterogeneous groups of actors, i.e. science, politics and industry, can facilitate interactive innovations. This project investigated how this was accomplished in practice in the context of cross-disciplinary technology development in hospitals. The dissertation is based on a longitudinal study of the Interventional Centre, Oslo University Hospital, Rikshospitalet, Norway.

This is one of the few systems available in the world for completely non-invasive (without any inonizing radiation involved) treatment of Uterine Fibroids [Figure 1]. Patients treatment is about to be started in a few weeks.MRgHIFU [2,3] may be a disruptive technology in the future by its total non-invasiveness compared to surgery or even radiation therapy where unwanted ionising radiation dose deposits always is an issue. Thus, target tissues (fibroids and tumours) can be destroyed without any device insertion in the body.

The Interventional Centre will be responsible for research and training in MR image guided cardiovascular procedures. The Interventional Centre will participate both as a clinical and technological partner in this field. Research will include new concepts to improve the intraoperative MR suit and the hybrid angiographic room through the development of new intraoperative image navigation tools. Ole Jakob Elle and Per Kristian Hol will coordinate the participation from IVC at a technological and clinical level respectively, and Frederic Courivaud will be responsible for the MR-related technology development. IVS will be funded by 74 person months and given a total budget of  approximately 4 mill NOK over four years by the project. The funding might be subject to changes through negotiations with the European Commision.

The SCATh-project was initiated by one of the ARISER partners (Katholieke Universiteit Leuven) by Jos Vander Sloten and Mauro Sette. The Interventional Centre is as a partner responsible for the development of catheter tracking/navigation in MR and clinical application and relevance. From The Interventional Centre Ole Jakob Elle will coordinate the IVC participation, with Frederic Courivaud responsible for the MR technology, Per Kristian for radiological aspects and Jacob Bergsland responsible for cardiac applications. IVS will be funded by 54 person months and given a total budget of approximately 3,7 mill NOK over four years by the project.

The sensors represents various stages of research based,experimental product development at the Interventional Centre. The sensors presented were a 3-axis accelerometer, an ultra sound sensor and a pCO2 sensor (Alertis Medical). All sensors represent a new type of sensors capable of local ischemia detection from heartbeat to heartbeat. The accelerometer and the ultra sound sensors are also able to detect changes in ventricular contraction patterns.
