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.

Johnson & Johnson MedTech launches new 2D ICE catheter
The company says the new device was designed to improve image quality, provide additional maneuverability and simplify ablation workflows for electrophysiologists.
Johnson & Johnson MedTech ordered to pay $147M for antitrust violations
The company told Cardiovascular Business it respectfully disagrees with the jury's decision and is evaluating all possible legal options going forward. The Association of Medical Device Reprocessors, meanwhile, celebrated the news.
Cardiologists are first in world to use new cooling device to terminate AFib during surgery
Patients often develop AFib during cardiac surgery, leading to longer hospital stays, additional healthcare costs and a higher risk of mortality. Cooling the oblique sinus of the patient's heart as soon as AFib starts to develop may represent a new way to stop the problem in its tracks.
World’s first leadless LBBAP procedures linked to ‘promising’ outcomes
Cardiologists are turning to leadless pacemakers more and more for cardiac pacing, but those devices have not previously been able to perform LBBAP. This new analysis includes new data on the world’s very first leadless LBBAP procedures.
AI predicts LBBB risk in TAVR patients prior to treatment
The authors tested out a variety of machine learning techniques, including large language models and more traditional algorithms. They focused on data that can be gathered prior to treatment, ensuring cardiologists know as much as possible before the procedure.

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.

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.

Elevated uric acid levels linked to new-onset AFib

According to new data published in the Journal of the American Heart Association, atrial fibrillation can be added to the list of cardiovascular conditions associated with above-average uric acid levels.

Damar Hamlin update: Buffalo Bills safety now communicating with doctors after cardiac arrest

“This marks a turning point in his ongoing care,” one doctor said in a statement.

Buffalo Bills safety Damar Hamlin went into sudden cardiac arrest after a tackle during the first quarter of the game between the Cincinnati Bengals and the Buffalo Bills at Paycor Stadium in Cincinnati Jan 2, 2023. The incident has instantly raised awareness and brought sudden cardiac arrest to the forefront on news reports today. Image from Buffalo Bills

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.

Medtronic reaches milestone in study of pulsed-field ablation and mapping catheter for AFib

A randomized study of more than 450 patients with persistent atrial fibrillation is now underway. All patients have been treated, and their outcomes will be tracked for 12 months.
