A miniature pacemaker developed for use in infants and those with limited vascular access has passed a proof-of-concept simulation and is entering its second phase of testing, researchers from Children’s National Health System in Washington, D.C., have reported.

Physicians who have financial relationships with biomedical manufacturers are up to 12 times more likely to use an implantable cardioverter-defibrillator (ICD) or cardiac resynchronization therapy-defibrillator (CRT-D) from that company instead of another manufacturer, according to preliminary research presented at the American Heart Association Scientific Sessions in Chicago.

When approached again, about a quarter of patients with atrial fibrillation (AFib) not taking anticoagulants due to physician-cited “patient refusal” said they would consider taking the drugs, according to preliminary research presented at the American Heart Association’s Scientific Sessions in Chicago.

For patients with nonvalvular atrial fibrillation (AFib), taking a direct oral anticoagulant (DOAC) instead of warfarin may cut the risk of dementia by 15 to 20 percent, according to a large database study published Nov. 2 in the Journal of the American Heart Association.

Mandatory CPR training in high school may contribute to higher rates of bystander intervention and improved survival following out-of-hospital cardiac arrest (OHCA), according to a registry study slated to be presented Nov. 11 at the American Heart Association’s Resuscitation Science Symposium in Chicago.

The American College of Cardiology, American Heart Association and Heart Rhythm Society on Nov. 6 released a new guideline for the evaluation and treatment of patients with bradycardia and cardiac conduction disorders.

A London, Kentucky, cardiologist was sentenced to 42 months in federal prison Oct. 31 after reportedly implanting “dozens” of unnecessary pacemakers and defrauding both his patients and their insurers, U.S. Attorney Robert M. Duncan, Jr., has announced.

A Stanford- and Apple-led atrial fibrillation study of more than 400,000 U.S. residents—the largest AFib screening effort to date—has entered its final phase of data collection, the company announced Nov. 1. The trial is expected to wrap up early next year.

An augmented reality (AR) technique involving 3D visualization of myocardial scar can assist physicians in evaluating and treating cardiac damage during electrophysiological interventions like ventricular tachycardia (VT) ablation, researchers reported in PLOS One.

Patricia V. Blake will take over as CEO of the Heart Rhythm Society (HRS) next March, HRS leadership announced Oct. 26.

Higher ejection fractions (EFs) among heart failure patients are associated with an increased incidence of atrial fibrillation (AF) and worse cardiovascular outcomes, according to data from a multinational European registry.

Medtronic co-founder Earl Bakken, who invented the world’s first wearable, battery-powered pacemaker, died on Oct. 21 in his Hawaii home, the company announced. He was 94.
