September 28, 2011 — The 24th annual International Symposium on Endovascular Therapy (ISET) will take place Jan. 15-19, 2012, at the Fontainebleau Miami Beach. More than 1,500 members of the global endovascular community will be in attendance; this includes physicians, researchers, scientists, biomedical engineers, nurses, technologists and other industry professionals. The fields of interventional radiology, interventional cardiology and vascular surgery will be represented, among others.

September 28, 2011 — A clinical trial by Resverlogix Corp. is evaluating the early effects of a new drug compound in atherosclerotic plaque regression. The study is focused on patients with coronary artery disease who have a low level of high-density lipoprotein cholesterol (HDL-C).

September 28, 2011 –Ziehm Imaging said its holding company Aton GmbH acquired 100 percent of the United States-based mini C-arm specialist OrthoScan Inc.

September 27, 2011 – Calgary Scientific Inc. has received clearance from the U.S. Food and Drug Administration (FDA) to market medical imaging application, ResolutionMD Mobile, as a mobile diagnostic application in the United States. With this secure, highly scalable, server-based software solution, physicians anywhere can rapidly access, view and interact with patient images and reports stored within any healthcare facility, and render a clinical diagnosis using their mobile devices. Prior non-diagnostic versions of this product are currently distributed and licensed under original equipment manufacturer (OEM) agreements with global leaders in medical imaging and information technology. In addition to the recent FDA clearance, ResolutionMD Mobile has also been licensed by Health Canada and bears the CE mark for distribution in Europe.

Toshiba will showcase its proprietary non-contrast magnetic resonance (MR) angiography imaging techniques and a new application of Time-Spatial Labeling Inversion Pulse (Time-SLIP) at the 2011 Radiological Society of North America (RSNA) trade show. To evaluate cerebrospinal fluid (CSF) flow disorders in children and adults, Time-SLIP can visualize CSF flow without the administration of contrast media, making imaging safer for patients.

Toshiba will showcase the Vantage Titan 3.0T MR system at the 2011 Radiological Society of North America (RSNA) trade show. The machine is equipped with multi-phase transmission technology, creating the most homogeneous abdominal and pelvic images on 3.0T systems.

September 27, 2011 — AccessClosure Inc. announced the shipment of its one millionth Mynx unit. The Mynx Vascular Closure Device received U.S. Food and Drug Administration (FDA) approval in May 2007, following with its full commercial launch in September 2007.

September 27, 2011 – Health 2.0 announced the launch of the Novartis CardioEngagement Challenge, asking multi-disciplinary teams of developers to create an interactive solution enabling patients to better manage their cardiovascular health through a customizable, user-friendly interface.

T-wave alternans (TWA) refers to an alternating pattern in the T-wave of the electrocardiogram (ECG) and is recognized as a marker of electrical instability.  Visible or macroscopic alternans was first reported in the context of proarrhythmic conditions including Prinzmetal’s angina and long QT syndrome, and was often found to immediately precede the onset of ventricular tachycardia or fibrillation.  More recently, techniques have been developed to measure microvolt-level T-wave alternans (MTWA) not visible to the human eye.  The presence of MTWA has been linked with increased risk of sudden cardiac arrest (SCA) in several patient populations.  This study presents the case of a patient who experienced VF during the recovery phase of an MTWA stress test.  While there was no visible abnormality on the ECG which would alert to the impending arrhythmia, significant microvolt-level alternans was detected immediately prior to the cardiac arrest.
