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.

The U.S. Food and Drug Administration (FDA) has granted the first pediatric indication for use for an implantable cardiac monitor to Medtronic. The Linq II Insertable Cardiac Monitor (ICM) system is the first such device receive 510(k) clearance for use in pediatric patients over the age of 2 who have heart rhythm abnormalities and require long-term, continuous monitoring.

FDA grants new pediatric indication for Medtronic Linq II implantable cardiac monitor 

The FDA granted the first pediatric indication for an implantable cardiac monitor. The Linq II can be used in pediatric patients over the age of 2 for up to 4.5 years of long-term, continuous monitoring.

New expert guidelines highlight the importance of quickly diagnosing and treating CIED infections

Though removal of the affected CIED is typically the smartest treatment option—and one supported by specialty groups all over the world—a majority of patients keep living with the device, often resulting in hospitalization or even death.

Affera Inc Medtronic $925 million catheter ablation atrial fibrillation (AFib)

Medtronic completes acquisition of heart rhythm tech company in a deal reportedly worth $925M

Affera’s portfolio includes interventional solutions such as the Affera Prism-1 mapping and navigation platform, designed to help electrophysiologists diagnose heart rhythm issues, and the Sphere-9 cardiac ablation catheter.

Rethinking arrhythmias: Women may face a higher AFib risk than men

New research, published in JAMA Cardiology, challenges the common belief that AFib is more likely to develop among men than women. The key problem, it seems, is that prior research teams did not understand the significance of certain risk factors.

Medtronic EV ICD clinical trial safety endpoints ESC Congress 2022
