Electrophysiology & Arrhythmia

 

Asymptomatic atrial fibrillation (AFib) patients could be at a heightened risk for cardiac complications, especially if the condition is paroxysmal, a study published in CHEST reports.

Artificial intelligence (AI)–assisted electrophysiology (EP) shows promise, but even its most ardent advocates aren’t ready for full-fledged endorsement—yet.   

The FDA issued a safety alert Jan. 17 for the Zoll LifeVest 4000, saying the external, wearable cardioverter defibrillator may fail to treat potentially fatal arrhythmias if it displays a specific error message which, by itself, doesn’t signal urgency.

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.

Contrast protocol assists 3D clarity in MR angiography
In MR angiography (MRA) of peripheral arteries, injecting contrast medium at a slow, balanced rate can alleviate contamination of veins in the calves while maintaining image quality, according to a multinational team of researchers from China and the United States. Their study, published this month in the American Journal of Roentgenology, suggests that it is possible to increase arterial visibility in the calf while signal-to-noise and contrast-to-noise ratios at higher levels are maintained.

Burning Question: Does Laser Heart Therapy for Angina Really Work?

In 1996, physicians told Pat Gibbs, a 67-year-old cardiac patient from Alabama with severe angina, that nothing could be done for her. Refusing to give up, Gibbs underwent transmyocardial laser revascularization (TMR) therapy and today, lives pain-free. Some cardiologists say TMRs benefit is merely a placebo effect, others say it is real. A growing market for the procedure, however, could muzzle the naysayers.
