A study in the March 24/31 issue of JAMA found that using balloon-expandable stents to treat symptomatic intracranial arterial stenosis resulted in an increased risk of stroke or transient ischemic attack (TIA). The study results support the use of medical therapy (clopidogrel and aspirin) as an alternative to balloon-expandable stents.

atients with atrial fibrillation (AF) who received ablation while they were already undergoing surgery to correct a leaky mitral valve had fewer episodes of AF a year later compared to patients who had the valve surgery alone. This was according to a study presented at the American College of Cardiology (ACC) 2015 meeting.
 
radiation, risk, cancer patients, information, Memorial Sloan Kettering, MSKCC

A new study published online in the journal Radiology found a substantial gap between patient expectations and current practices for providing information about medical imaging tests that use radiation. Researchers said the findings highlight a need for better communication as medicine enters an era of patient-centered care.
Patients over age 80 with acute coronary syndromes would likely benefit from more invasive tests and therapies that may otherwise be denied them due to their age, according to research presented at the American College of Cardiology (ACC) 2015 annual meeting.
 

atients with acute coronary syndrome undergoing angioplasty who received the anticoagulant drug bivalirudin did not show significant improvements in either of two coprimary endpoints — a composite of rate of death, heart attack or stroke at 30 days, or a composite of those events plus major bleeding — as compared to patients receiving standard anticoagulation therapy, according to a study presented at the 2015 American College of Cardiology (ACC) meeting.
low-dose radiation, cancer risk, mice, Berkeley National Laboratory, therapy, CT

Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory  have uncovered new clues about the risk of cancer from low-dose radiation. In this research, low-dose is defined as equivalent to 100 millisieverts or roughly the dose received from 10 full-body computed tomography (CT) scans.

TomTec Imaging Systems GmbH announced U.S. Food and Drug Administration (FDA) 510(k) clearance for the latest version of its TomTec-Arena software solution.

Biotronik announced that the U.S. Food and Drug Administration (FDA) has approved its ProMRI Eluna pacemaker system. Biotronik ProMRI technology allows patients to undergo full-body magnetic resonance imaging (MRI) scans with both single-chamber (SR-T) and dual-chamber (DR-T) Eluna pacemakers when implanted with Setrox pacing leads.

AtriCure Inc. announced that it has launched the availability of its cryoICE cryo ablation probe (CRYO2) to provide cryoanalgesia for temporary pain management. AtriCure’s cryoICE is the first U.S. Food and Drug Administration (FDA)-cleared cryo ablation probe for the treatment of cardiac arrhythmias and for the temporary ablation of peripheral nerves to block pain.
