Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

Medtronic Surescan(r) pacing systems first to be approved for full body MRI scans without positioning restrictions

Medtronic, Inc. (NYSE: MDT), today announced that the Medtronic SureScan(r) pacing systems - the first and only pacing systems in the United States that have been approved by the U.S. Food and Drug Administration (FDA) for use with magnetic resonance imaging (MRI) - are now approved for MRI scans positioned on any region of the body. Patients implanted with the Advisa DR MRI(r) or Revo MRI(r) SureScan pacing systems now can have MRI scans without positioning restrictions, including the chest area, which previously had been restricted.

New Kcentra label includes urgent reversal of warfarin in an emergency surgery setting

CSL Behring today announced that Kcentra® (Prothrombin Complex Concentrate [Human]) has received U.S. Food and Drug Administration (FDA) approval for an expanded indication -- urgent reversal of acquired coagulation factor deficiency induced by vitamin K antagonist (VKA, e.g., warfarin) therapy in adult patients needing an urgent surgery or other invasive procedure. Kcentra, approved by the FDA in April 2013 for the urgent reversal of warfarin therapy in adult patients with acute major bleeding, is the only non-activated 4-factor prothrombin complex concentrate (4F-PCC) indicated in the U.S. for these uses.

Management of atrial fibrillation still suboptimal in Europe

Results for a pilot registry on the management and treatment of atrial fibrillation (AF) in Europe were presented yesterday by the European Society of Cardiology (ESC). AF is the commonest cardiac rhythm disorder and each of us have a one-in-four lifetime risk of developing it. Statistics show that oral anticoagulant use has increased, but new oral anticoagulant (NOAC) use is still low. Authors also concluded that compliance with treatment guidelines for patients with the lowest and higher stroke risk scores remains suboptimal.

Data indicate the antidote may be able to achieve immediate, complete and sustained reversal of dabigatran-induced anticoagulation in healthy humans

Boehringer Ingelheim Pharmaceuticals, Inc. today announced results showing that its investigational fully humanized antibody fragment (Fab) rapidly reversed the anticoagulation effect of dabigatran in healthy male volunteers. These results, presented today during the American Heart Association's Scientific Sessions 2013, represent the first clinical data involving the compound, which was discovered and developed by the company (ClinicalTrials.gov Identifier: NCT01955720).

Around the web

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
