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.

Medical device startup gains FDA clearance for new RF guidewire, raises $12.5M
Atraverse Medical, a San Diego-based medical device company founded in 2022, designed the guidewire to give physicians as much freedom as possible while treating heart patients.
Cardiology ranked No. 2 among all specialties with 122 FDA-cleared AI models
Only radiology is associated with more FDA-cleared AI algorithms than cardiology, according to new federal data.
Medtronic adds new AI models to its insertable cardiac monitors
The new algorithms are automatically applied in the cloud; patients wearing the devices are not required to take any additional steps.
World’s first dual-chamber leadless pacemaker still going strong after 6 months
Abbott’s Aveir DR leadless pacemaker, the first pacing offering of its kind to gain FDA approval, is linked to a consistent electrical performance six months after implant. Researchers tracked data from nearly 400 patients and presented their full findings in Heart Rhythm.

Extracorporeal CPR for out-of-hospital cardiac arrest: New research fails to provide answers

While a previous study had found that extracorporeal CPR outperformed conventional CPR among patients with out-of-hospital cardiac arrest, a newer analysis suggests the two treatment options result in similar outcomes.

An example if an implantable cardioverter defibrillator (ICD and its leads connected to the heart. As the leads or deveice wears out, there are recommendations to remove the leads and put in new ones. The most common causes of mortality during transvenous lead removal (TLR) in patients with cardiac implantable electronic devices (CIEDs) are infection and decompensated heart failure, according to new research published in JACC: Clinical Electrophysiology.Image courtesy of RSNA

Infection, heart failure the most common reasons for early mortality after transvenous lead removal

Early mortality specifically related to complications during the TLR procedure was quite rare.

Most devices implanted during LAAO procedures are oversized—and patients benefit

Oversized devices are becoming more common as time goes on, which suggests operators are growing increasingly comfortable with this treatment choice.
