Electrophysiology

The cardiac subspecialty of electrophysiology (EP) diagnoses and treats arrhythmias. This includes use of pacemakers to treat bradycardia, implantable cardioverter defibrillators (ICD) for tachycardia, heart failure and patients at risk of sudden cardiac arrest, and cardiac ablation treatments to treat heart rhythm disorders.

Low BMI increases risk of cardiac tamponade during AFib ablation

Also, researchers noted, cryoballoon ablation was linked to a lower risk of cardiac tamponade than radiofrequency ablation. The study included data from nearly 60,000 hospitalizations.

AI model uses DNA to predict AFib, heart failure

Scientists were able to identify a total of 21 genes linked to cardiovascular conditions such as AFib and heart failure.

The increased use of implantable loop recorders (ILRs) is associated with identifying more bradyarrhythmias such as bradycardia, according to new findings published in JAMA Cardiology.

Increased AFib screening improves bradyarrhythmia detection—but is it a mixed blessing?

When long-term continuous monitoring detects bradyarrhythmia in an asymptomatic patient, is it still providing value?

Medtronic shared some good news with attendees at ESC Congress 2022 in Barcelona, the annual meeting of the European Society of Cardiology, noting that its Extravascular Implantable Cardioverter Defibrillator (EV ICD) system met its safety endpoints in a global clinical trial.

Medtronic’s new extravascular ICD gains key approval

Unlike other ICDs, the lead for this new-look device is placed under the patient's breastbone, outside of their heart and veins.

A 3D intracardiac echo (ICE) view of a surgical mitral valve using the NuVision ultrasound catheter developed by Biosense Webster in partnership with GE Healthcare.

Can intracardiac echo replace TEE during structural heart procedures?

TEE has been used to guide most transcatheter structural heart cases over the past decade, but 3D ICE is changing how some centers image those patients.

He led a team of engineers at the University of Missouri (UM) to develop a new soft, stretchable material that could potentially be used in wearable devices that gather key cardiovascular data. The group shared its findings in Science Advances, noting that the material creates such a small amount of pressure that users will not even notice they have it on.

Researchers design new material for wearable devices: ‘You cannot feel it, and you will likely forget about it’

The soft, stretchable material creates so little pressure that users will likely not even even be able to feel it.

AI model predicts risk of post-operative AFib

Post-operative atrial fibrillation was once viewed as a fairly insignificant issue, but more recent research suggests it can increase a patient’s risk of multiple adverse events.

Abbott gains new FDA approval for one catheter, CE mark approval for a second catheter

Both devices were approved for treating significant heart rhythm issues.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
