October 17, 2007 - Compared to bare metal stents, in patients with acute myocardial infarction, sirolimus-eluting stent (SES) implantation aggravates endothelial vasomotor dysfunction in the infarct-related coronary artery, Japanese researchers report in the October 2nd issue of the Journal of the American College of Cardiology.

Kiyotaka Kugiyama, M.D., and colleagues at the University of Yamanashi, Chuo City note that drug-eluting stents reduce restenosis rates and revascularization but may impair recovery from reperfusion-induced endothelial injury.

October 17, 2007 - After a three-week trial, a jury rendered a verdict of "willful" patent infringement in a dispute filed against CHF Technologies, Inc., d/b/a BioVentrix, after Chase Medical sued BioVentrix alleging its Blue Egg Sizer, a hollow, blue silicone device used to guide surgeons in surgically resizing the heart, infringed patents held by Chase.

October 17, 2007 - Positron Corp. introduced its new dedicated-Cardiac PET system, Attrius, at the annual meeting of the American Society of Nuclear cardiology, for which it expects to receive 510k FDA approval in spring of 2008 in time for proposed cardiac PET reimbursement increase on Jan 1, 2008.

October 17, 2007 – Siemens Medical Solutions today announced that it recently received FDA 510(k) clearance for a 1.5 Tesla (T) magnetic resonance imaging (MRI) system that is reportedly more affordable, allowing providers to upgrade from low-field MRI systems or to add an MRI system for the first time.
The cost of the new 1.5T MAGNETOM Essenza can reportedly be as much as $500,000 less than other 1.5T systems, making it possible for small hospitals and diagnostic imaging centers to offer a new range of imaging services.

The FDA gave ZOLL Medical Corp., a manufacturer of resuscitation devices and related software solutions, clearance to market and sell the ZOLL AED Pro with See-Thru CPR technology, which is designed to help minimize interruptions in CPR.
ZOLL aims to comply with a key recommendation of the American Heart Association’s Guidelines for Advanced Cardiac Life Support.

The FLAIR Endovascular Stent Graft treats stenoses (narrowing) at the venous anastomosis of synthetic arteriovenous (AV) grafts in hemodialysis patients to increase blood flow.

The KODAK DIRECTVIEW Classic and Elite Computed Radiography Systems are compact, floor standing, single-cassette CR systems that can reportedly help improve workflow, productivity and patient throughput.
The systems, offering a modular design, are significantly smaller than other DIRECTVIEW single-cassette systems and reportedly incorporate the latest generation of CR software from Carestream Health. These systems use existing rigid cassettes to support general radiography exams, long-length imaging and dental applications as well as mammography exams.

Agfa HealthCare’s DX-S reportedly fills the gap in the current range of Digital Radiography Solutions by providing a unique combination of image quality, speed and flexibility that exceed traditional CR solutions.

The Philips Step and Shoot Cardiac solution has reportedly been shown to save up to 80 percent of the dose in a cardiac exam. As the newest cardiac imaging innovation for the Philips Brilliance CT 64-channel scanner, it provides high quality CT images at low radiation dose. An axial prospective ECG-gated acquisition technique reportedly achieves full heart coverage within a short breath-hold.

Building on the foundation of GE Healthcare’s CT platform, the LightSpeed VCT XT is reportedly capable of capturing images of the heart and coronary arteries in as few as five heartbeats. With SnapShot Pulse, the LightSpeed VCT XT reduces a patient’s X-ray exposure time by up to 70 percent for diagnostic cardiac scans, using a process called prospective triggered gating.
