In a move that will likely have a significant impact how many patients are treated for carotid artery disease, the U.S. Food and Drug Administration (FDA) has cleared the use of a stent to treat standard-risk surgical patients. Prior to the approval, carotid stenting was only indicated for used in high-risk surgical patients who were often denied the standard-of-care of carotid endarterectomy surgery.

May 6, 2011 – New data presented at the Society for Cardiovascular Angiography and Interventions (SCAI) Scientific Sessions are the first to look at the use of highly specialized signals within implantable cardioverter defibrillators (ICDs) to detect restricted blood flow to the heart in high-risk cardiovascular disease patients outside the hospital setting. Preliminary results from the ST-DETECT Trial using high-fidelity intracardiac electrogram (EGM) signals in ICDs show a low spontaneous coronary event rate (such as heart attack) among these patients.

May 6, 2011 – Results from an analysis of the ALTITUDE Clinical Science program demonstrated that defibrillator therapy saves lives from lethal arrhythmias without an increase in mortality due to defibrillator shock. Instead, the authors found that increased mortality risk associated with these shocks is not attributed to the defibrillator shock itself, but rather to the underlying medical condition leading to atrial and ventricular arrhythmias.
