Electrophysiology & Arrhythmia

 

Roughly 1 in 4 children with Brugada syndrome treated with implantable cardioverter-defibrillators (ICDs) received life-saving shock therapy in a single-center study of 35 patients published in the Journal of the American College of Cardiology. However, 20 percent experienced inappropriate shocks and another 14 percent had device-related complications, highlighting the challenging clinical decision-making in this high-risk group.

Analyzing the change in stroke risk factors for atrial fibrillation (AFib) patients was far more powerful in predicting stroke than assessing baseline risk factors alone, researchers reported in the Journal of the American College of Cardiology.

Longtime claims that heart patients fitted with implantable cardiac devices should forgo MRI testing for safety concerns could be incorrect and “outdated,” according to new research published in the New England Journal of Medicine.

When writing about a recent JAMA Cardiology study, I was struck by an image of former Loyola Marymount University basketball star Hank Gathers swinging from the rim after a powerful dunk—and then collapsing to the court seconds later. Gathers died at 23.

New technology developed at New York’s Binghamton University could change the way clinicians detect heart disease with MRI scans, research published in the journal Colloid and Surfaces B: Biointerfaces suggests.

Pacemaker Predicaments: Reining in Implantation Rates in Low-risk TAVR

The need for permanent pacemakers in patients with severe aortic stenosis who undergo transcatheter aortic valve replacement (TAVR) remains a complication, even as TAVR expands into lower-risk groups. That may prove to be a limitation, especially with younger patients who may have decades of life ahead of them.

Octoberfest study suggests association between acute alcohol consumption and cardiac arrhythmias

An analysis conducted at the Munich Octoberfest found that acute alcohol consumption was associated with sinus tachycardia and other cardiac arrhythmias.

Patients with low health literacy may be less aware of their atrial fibrillation diagnosis

After adjusting for sociodemographics, health behaviors and clinical characteristics, patients with atrial fibrillation who had low health literacy were less likely to be aware of their diagnosis, according to an analysis of members from two large health insurance companies.

ICDs may decrease all-cause mortality in patients with nonischemic cardiomyopathy

A meta-analysis of four randomized trials found that using primary prevention implantable cardioverter defibrillators (ICDs) decreased all-cause mortality by 25 percent in patients with nonischemic cardiomyopathy.

Only 17 states require at least some schools install AEDs

Although research has shown automated external defibrillators (AEDs) can increase survival after cardiac arrest, only 17 of 50 U.S. states required at least some of their schools install AEDs as of February 2016, according to a database analysis.

Phillips recalls 47,000 units of its HeartStart MRx monitor/defibrillator

Phillips recalled the HeartStart MRx monitor/defibrillator after discovering electrical and battery connection issues that could prevent the device from powering up, charging and delivering an electrical shock therapy.

ACC.17: Digoxin use may increase the risk of death in patients with atrial fibrillation

Patients with atrial fibrillation and at least one additional risk factor for stroke who received digoxin had higher mortality rates compared with those who did not take digoxin, according to an analysis of a randomized trial.

BioSig Technologies agrees to partnership with two Mayo Clinic electrophysiologists

BioSig Technologies announced an agreement to work with two Mayo Clinic cardiac electrophysiologists to develop features and applications for the company’s PURE EP system.

85% of atrial fibrillation patients receive inadequate anticoagulation prior to stroke

Nearly 85 percent of patients with a history of atrial fibrillation who had an acute ischemic stroke did not receive guideline-recommended anticoagulation or had anticoagulation levels that did not fall in the therapeutic range, according to a registry analysis.
