Arrhythmia Disorder
Mapping catheter for cardiac arrythmias cleared, launched
Biosense Webster announced the launch of an FDA-cleared catheter with novel technology for mapping cardiac arrythmias, including atrial fibrillation.
PRE-DETERMINE: Polygenic score predicts risk for sudden cardiac death in CAD
A validated genome-wide polygenic risk score predicted clinically meaningful absolute risk for sudden arrhythmic death in a cohort of patients with CAD without severe left ventricular dysfunction, researchers reported.
FDA designates recall of ICD, CRT devices as class I
The FDA announced Medtronic has issued a recall of its implantable cardioverter defibrillators and cardiac resynchronization therapy devices due to a short circuit protection alert resulting in reduced-energy electric shock delivery.
Simulation model: Wearable devices cost-effective for AF screening
In a microsimulation decision-analytic model, wrist-worn devices were cost-effective at screening for atrial fibrillation compared with traditional modalities or no screening.
Analysis: Postoperative AF just as dangerous as nonoperative AF
The risk for stroke and other poor outcomes was similar in patients with postoperative atrial fibrillation after noncardiac surgery and in patients with AF not associated with surgery, researchers reported.
Early rhythm control beneficial vs. rate control in AF, but effect may decrease with age
In patients younger than 75 years with atrial fibrillation and concomitant CV conditions, an early rhythm control strategy was associated with better CV outcomes compared with a rate control strategy, researchers reported.
Early rhythm control for AF beneficial for older patients with high comorbidity burden
In patients with recently diagnosed atrial fibrillation and a high comorbidity burden, early rhythm control therapy markedly reduced CV death, stroke or hospitalization for HF or ACS, according to new data from the EAST-AFNET 4 trial.
Smartwatch heart data less accurate for people with darker skin tones
WASHINGTON — Wearable devices may be less accurate for the detection of heart rate and rhythm in adults with darker skin tones, according to data from a meta-analysis presented at the American College of Cardiology Scientific Session.
Heart rhythm monitor implanted after MI does not prevent CV events
WASHINGTON — In patients with MI at high risk for stroke, implanting a loop recorder did not impact subsequent CV events, according to the results of the BIO | GUARD-MI trial.
Dual-chamber leadless pacemaker implanted for first time in US
The first pacemaker implantation was performed in 1958, and the technology has undergone many advances since then, the latest being a dual-chamber leadless system.
